TOOL1649 4-Deep Inwater Imaging HoloSea S7 submersible holographic microscope A submersible holographic microscope for use in water profiling and monitoring applications, as well as particle, phytoplankton and zooplankton imaging for counts and morphological analysis. It outputs up to 22 images per second in real-time. It uses the principle of digital inline holography (DIH) to produce enlarged images of an object and its 3D structure. A laser is directed into a pinhole from which a spherical wave emanates. The wave illuminates the object and forms a geometrically magnified diffraction pattern on a charged couple device (CCD) screen. The interference pattern produced is displayed as a hologram stored as a digital image. The 3D structure of the object from the 2D hologram is reconstructed using a numerical algorithm (Kirchhoff���Helmholtz transform). The HoloSea S7 can be towed at 8 knots. The laser light source has a wavelength of 405 nm. It is pressure rated to 500 m with a cable depth of 100 m, but custom 6000 m rated models are also available. 2021-03-12

TOOL1064 Active Microwave Instrument An active microwave instrument consisting of a synthetic aperture radar (SAR) and a wind scatterometer (SCAT), the former designed to capture imagery of ocean, land and ice at high resolution and independently of weather conditions, and the latter utilised to measure horizontal wind speed and wind vector over the surface, as well as soil moisture and sea-ice type. The SAR radar operates by obtaining strips of imagery in two modes: the imaging mode, and the wave mode. In imaging mode, SAR provides two-dimensional images between (6 - 30)m along-track at a spatial resolution of 26m. In wave mode, imagettes of 5 km by 5 km in size are captured at regular intervals of 200 km along track; the imagettes are then processed within the swath to obtain the wave spectra, as changes in radar reflectivity on the sea surface are proxies for length and direction of surface waves. SCAT is composed by three sideways-looking antennae which generate radar beams at 45, 90 and 135 degrees azimuth across a swath 500 km wide situated 200 km to the right of the sub-satellite track. The radar backscatter is then measured for overlapping cells of 50 km resolution, using a grid spacing of 25 km. This technique permits three different viewing directions almost simultaneously, facilitating the determination of surface wind vectors. SAR and SCAT can be operated together, unless SAR is in imaging mode. The wave direction detected range is (0 - 180) degrees, at an accuracy of +/- 20 degrees; the detected wavelength range is (100 - 1000)m, with an accuracy of +/- 25%. AMI-SAR operates at the C-band frequency of 5.3 GHz with a bandwidth of 15.5 MHz, using vertically polarised antennas. The spatial resolution achieved is 30 m over a 100 km swath, located 250 km to the right of the sub-satellite track; the look angle is 23 degrees. Wind direction detected range is (0 - 360) degrees, at an accuracy of +/- 20 degrees; wind speed detected range is (4 - 24) m/s, at an accuracy of 2 m/s and spatial resolution of 50 km. AMI-SCAT operates at the C-band frequency of 5.3 GHz +/- 200 kHz.

TOOL1061 Advanced Along-Track Scanning Radiometer A passive optical imager with dual view composed of a 7-channel infra-red radiometer, designed to measure sea surface temperature, cloud attributes, as well as vegetation and sea-ice cover. The infra-red radiometer uses an along-track scanning telescope to focus incoming radiation from two views at different angles: one at nadir and one fore-looking at approximately 47 degrees. The same point on the Earth's surface is thus observed twice through differing atmospheric thickness, allowing for direct estimation of the atmospheric absorption and scattering, which can be used for atmospheric correction of the surface dataset. The instrument carries an on-board visible calibration system. The AATSR is functionally identical to ATSR-2, but its structure is adapted to the Envisat platform. Moreover, AATSR has a larger telemetry bandwidth compared to ATSR-2, allowing it to collect and telemeter a greater amount of visible data. The instrument's bandwidths are: (0.53 - 0.57)um, (0.64 - 0.68)um, (0.85 - 0.89)um, (1.31 - 1.91)um, (3.55 - 3.85)um, (10.35 - 11.35)um, (11.50 - 12.50)um.

TOOL1067 Advanced Microwave Sounding Unit - A A multi-channel microwave radiometer designed to measure global atmospheric temperature profiles in nearly all weather conditions. AMSU-A samples thirty consecutive scene radiances in a stepped-scan fashion every eight seconds, and measures the atmospheric temperature profile by examining fifteen bands of microwave radiation ranging between (23 - 90) GHz. The instrument consists of two independent modules with their own spacecraft interface: AMSU-A1 and AMSU-A2. AMSU-A2 identifies precipitation and corrects for surface emissivity, atmospheric liquid water and water vapour effects by processing the first two microwave radiation channels using one antenna.

AMSU-B is a cross-track, line scanned instrument which samples ninety consecutive scene radiances in a continuous fashion, and measures atmospheric humidity profiles by examining five bands of microwave radiation ranging between (89.0 - 193.31)GHz. The instrument consists of a scanning parabolic reflector antenna which rotates and focuses incoming radiation from the atmosphere into a quasi-optic system. The frequencies of interest are then separated into three discreet feed horns of the receiver assembly. AMSU-B works in conjunction with AMSU-A to provide a twenty-channel microwave radiometer.

TOOL1070 Advanced SCATterometer A C-band scatterometer designed to detect wind speed and vector over the sea surface, as well as large-scale soil moisture. Three sideways-looking antennas located on both sides of the instrument transmit microwave pulses toward the sea surface and measure the ground echoes returned back to the instrument. The backscattering properties of the signal detected are related to wind-generated sea-surface roughness, and can thus be used to infer wind speed and direction. The three antennas on each side are oriented at 45, 90 and 135 degrees azimuth respectively, and scan two 500 km swaths separated by a 700 km gap along-track. ASCAT operates at the C-band frequency of 5.233 GHz. The spatial resolution is 50 km (nominal) or 25 km (experimental).

TOOL1069 Advanced Synthetic Aperture Radar A radio-occultation imaging radar designed to capture imagery of ocean, land and ice at high resolution and independently of weather conditions. The instrument operates as an active remote sensing device, emitting microwave pulses in the C-band frequency range (2 GHz - 4 GHz) and recording the response reflected by the Earth's surface targeted. The time it takes for each emitted pulse to return to the instrument holds information on the distance of the target object, whilst the amount of the signal returned is used to extract information on surface properties. ASAR operates in five mutually exclusive modes, which output images of different sizes and spatial resolution. The instrument is able to create orthogonal polarised waves, the return signal of which can be used to extract information on the type of surface targeted. The user can select an operating mode out of five mutually exclusive options: the Image mode (IM), generating products at a spatial resolution of 30 m over one of seven selectable swath widths determined by incidence angles between 15 degrees to 45 degrees, at horizontal transmit and receive polarisation (HH) or vertical transmit and receive polarisation (VV); the Alternating Polarisation mode (AP), generating products at a spatial resolution of 30 m over one of seven selectable swath widths determined by incidence angles between 15 degrees to 45 degrees, at different dual polarisation combinations (HH/VV or HH/HV or VV/VH); the Wide Swath mode (WS), which uses the ScanSAR technique, thus providing images at 150 m resolution over five combined sub-swaths covering a total of 405 km, in HH or VV polarisation; the Global Monitoring mode (GM), outputting 1 km resolution images over a 405 km swath, in HH or VV polarisation; and the Wave mode (WV), which generates backscatter vignettes of 5 km by 5 km size, spaced 100 km along track in HH or VV polarisation.

TOOL1427 Analytical Sciences Thermalox TOC and TNb (thermal oxidation) elemental analyser series A series of bench-top, thermal oxidation systems. The instruments are designed for use in aqueous systems and solids. They primarily measure Total Organic Carbon (TOC) and Total Nitrogen (TN). Analysers use catalytic thermal oxidation to convert carbon or nitrogen species to either carbon dioxide (CO2) or NOx gases. CO2 is analysed using non-dispersive infrared detectors.

TOOL1561 BellaMare LLC and University of Miami RSMAS In Situ Ichthyoplankton Imaging System {ISIIS} - Cowen and Guigand (2008) The ISIIS was developed in collaboration between the University of Miami's Rosenstiel School of Atmospheric and Marine Science (RSMAS) and the subsea engineering company, Bellamare, LLC. Funding was provided by the National Science Foundation, NOAA, UNH Large Pelagics Center, and UM Maytag Chair of Ichthyology. ISIIS systems image organisms and particles in-situ as they swim or flow in between its two pods (fitted with a camera and illumination system). The instrument captures images of mostly undisturbed organisms, at a fine spatial and temporal resolution. ISIIS is an underwater imaging system for capturing in situ, real time images of marine zooplankton of relatively low abundance such as fish larvae and fragile gelatinous organisms. ISIIS imaging systems use industrial grade cameras. On towed sleds, they use a line-scan camera creating one single continuous image representing a real slice of the ocean. However, they can also be fitted with a classic area-scan camera if a system is to be used still (underwater monitoring station) or do slow vertical profiles. The ISIIS system utilizes a high-resolution line-scanning camera with a Light Emitting Diode (LED) light source, modified by plano-convex optics, to create a collimated light field to backlight a parcel of water. The imaged parcel of water passes between the forward portions of two streamlined pods (UW housings), and thereby remains unaffected by turbulence. The resulting very high-resolution image is of plankton in their natural position and orientation. When a sufficient volume of water is imaged this way, quantification of density and fine-scale distribution is possible.

TOOL1251 British Antarctic Survey Shipboard Three Component Magnetometer A British Antarctic Survey-built shipboard three-component magnetometer. The design of this instrument was based on the STCM described by Korenaga et al., 1995; however, BAS's version is simplified, it does not use a gyrocompass, and records heave, roll and pitch information using an Ashtech 3D GPS and TSS300 HRP attitude sensor. One of the principles of the STCM is to simultaneously measure the ship's attitude and the magnetic vector field, in order to remove the effect of the ship's motion. In order to obtain unbiased ambient geomagnetic field measurements, the ship's own magnetisation needs to be known. This is obtained by carrying out 'figure eight' manoeuvres at constant speed, during which unbiased ship's rolling data can be acquired. 2018-08-02

NETT0185 British Antarctic Survey multiple plankton net system based on MOCNESS A British Antarctic Survey-built version of the Multiple Opening and Closing Net with an Environmental Sensing System (MOCNESS) originally designed by Wiebe et al. (1976) for capturing zooplankton. This version consists of nine nets, which can be towed to a maximum depth of 1000 m. A live data stream allows an operator on the ship to close a net, thus triggering the opening of the next one. The first net is open when the system goes in the water; when the maximum depth is reached, the operator triggers it to close, thus automatically prompting the next one to open. This mode of operation is repeated until all nets have collected samples. This system allows for accurate control over timing and location of samples, which are collected sequentially through the nine nets. The frame also carries a current meter and a CTD system. 2018-01-30

TOOL0011 Bubbler tide gauge The full tide bubbler system normally consists of two independent measuring systems. The pressure points are mounted approx 1m below Admiralty Chart Datum (ACD) so that negative surges may be recorded and are similar in appearance to an inverted bucket with a copper nozzle mounted on the side. This nozzle is the actual measuring point. A low flow of dry air (normally 7ml/min) is fed down an air tube to the top of the pressure point. When the air pressure in the air line equals the pressure exerted by the column of water above it, then the excess air is released as bubbles through the copper nozzle. This means that the pressure in the air line is proportional to the weight of the water column. 2008-11-28

TOOL1689 Chelsea Technologies Group UV Aquatracka fluorometer An in situ fluorimeter designed to monitor concentrations of hydrocarbons (360nm) and Gelbstoff (440nm). The instrument may be mounted on a towed vehicle such as Chelsea Technologies Group's AQUAshuttle III, NvShuttle or SeaSoar, it can be deployed on buoys, on a mooring, or vertically in a profiling mode. The fluorimeter uses a pulsed light double beam technique. The pulsed technique allows virtually perfect discrimination to be achieved against "steady" ambient light signals since the light pulse is only two microseconds long, variations in ambient intensity due to wave glitter, etc. are considered "steady" by the high-speed processing circuits and are effectively rejected by the AQUAtracka. The double beam system allows the light intensity of the optical beam(X) returned from the specimen to be compared with the light intensity of the reference beam(Y) generated from the same pulsed light source. The outputs are then ratioed(X/Y) so that they are not affected by any variations in the flash lamp strength due to lamp ageing. The housing is constructed in titanium and the instrument is rated to 600m (option 6000m) and incorporates an optional ambient light baffling cowl. A fast response (300ms) platinum resistance Pt 100 Temperature Probe can also be included optionally.

TOOL0563 Cyclonic separation sampler A device designed to remove particulates from an air, gas or liquid stream through vortex separation. A high speed rotating flow is established within a vertical cylindrical or conical container, where the stream to be separated is fed in the top (wide) end, flows helically around the container to the bottom (narrow) end and then exits the cyclone in a straight stream through the centre and out the top. Instead of following the flow of the stream, the inertia of large (dense) particles causes them to hit the sides of the container and fall to the bottom, where they can be removed. The cyclone geometry and flow rate define a cut point, which is the size of the particle that will be removed from the stream with 50% efficiency. Larger particles will be removed with a greater efficiency and smaller particles with a lower efficiency. The sampler may be used in series with filters designed to collect different target particles. 2012-10-15

TOOL1487 Duncan and Associates Shipek grab A center-pivot sampler designed to sample unconsolidated sediments from soft ooze to hard-packed silts from deep lakes and near offshore. The sampler scoops a sediment sample from the top 10cm of the seabed. It brings up virtually un- disturbed, unwashed samples to the surface from any depth. Its specialty is sampling benthic organisms living at or immediately below the water/bottom interface and sediment containing a significant population of non-sessile forms. When the grab touches the bottom, inertia from a self-contained weight releases a catch and helical springs rotate the inner half cylinder by 180 degrees. After turning, the scoop remains closed by the residual torque of the scoop spring. Because the rotation of the bucket is very rapid, its shear strength is far greater than the sediment strength, thus cutting cleanly, particularly in soft clays, muds, silts and sands. Manufactured in 316 stainless steel with a sampling area of 0.042m sq. There is the option of adding a landing table. 2020-06-30

TOOL1423 EdgeTech 4200 Side scan Sonar The 4200 Series is a versatile side scan sonar system that can be configured for almost any survey application from shallow to deep water operations. The 4200 utilizes EdgeTechs Full Spectrum CHIRP technology to provide crisp, high resolution imagery at ranges 20-30% greater than non-CHIRP systems. A 4200 system comes with a choice of a dual simultaneous frequency towfish available in either a stainless steel or lightweight aluminium housing depending on operational requirements. Customers can also choose between a rack mount or portable topside processor or a digital link to interface to 3rd party topsides and software. One of the unique features of the 4200 is the optional Multi-Pulse (MP) technology, which places two sound pulses in the water rather than one pulse like conventional side scan sonar systems. This allows the 4200 to be towed at speeds of up to 10 knots while still maintaining 100% bottom coverage. In addition, the MP technology will provide twice the resolution when operating at normal tow speeds, thus allowing for better target detection and classification ability.

TOOL1696 EndRun Sonoma N12 GPS synchronised Network Time Server The Sonoma Network Time Server is a precision server of Coordinated Universal Time (UTC) that can be connected via an Ethernet port to any TCP/IP network. The GPS Subsystem in the Sonoma receives transmissions from satellites that are operating in compliance with the Navstar GPS Interface Control Document (ICD) known as GPS-ICD-200. The Sonoma is composed of a Global Positioning System (GPS) Subsystem containing the EndRun GPS Receiver and system oscillator. The receiver can relate the time-of-arrival of the received GPS transmissions from the satellite to GPS time. Monitoring, maintenance and control is accomplished by a wide range of protocols. Available timing protocols include: Network Time Protocol (NTP), Simple Network Time Protocol (SNTP), Time, Daytime, and the optional Precision Time Protocol (PTP/IEEE-1588). In its most basic operation, the Sonoma sends NTP reply packets in response to NTP request packets which it has received from clients. The timestamps it sends in its NTP reply packets are accurate to 10 microseconds, typical. Once synchronized, the Sonoma can maintain acceptable network synchronization accuracy for about a day without GPS reception. The instruments operating temperature range is 0 to 50 degrees Celsius. 2021-06-15

It is closed when deployed then opens automatically (hydrostatic pressure activated) at approximately 10 m and flushes until closed. When the bottle reaches the desired depth the lanyards are released by a pressure-actuated switch, command signal or messenger weight and the caps are forced shut and sealed. Bottles may be deployed singly clamped to a wire or in groups on a rosette. A reversing thermometer assembly may be attached to the bottle. When extracting water from the bottle, inert gas can be injected into the bottle to force the sample out of the sampling valve. The GO-FLO sampler avoids sample contamination at the surface, internal spring contamination, loss of sample on deck (internal seals), and exchange of water from different depths. 2012-06-21

TOOL1581 Hydroptic ZooSCAN imaging sensor The ZooScan (Gorsky et al., 2010) is a plankton scanner designed for benchtop applications. It produces and analyses high-resolution digital images of net or bottle-collected zooplankton samples in a fast and semi-automatic way. It allows collection of data on rapidly degenerating gelatinous plankton. The device uses scanner technology with custom lighting and a watertight scanning chamber into which the sample (liquid containing zooplankton organisms) can be placed. The scanner then makes a digital, high-resolution image of the sample enabling optimization of all objects above 200 &micro;m equivalent spherical diameter. Image resolution can be up to 4800 dpi (dots per inch) and each image is 14 150 pixels by 22 640 pixels and may contain hundreds to thousands of individual zooplankton organisms. The analysis is non-destructive since the liquid sample scanned can be recovered without damage through a drainage channel. The device also has built-in features making it possible to standardize the images of different ZooScans, to remote control the image generation, and to build a common image database. 2021-01-28

TOOL0405 National Marine Facilities Microelectrode Oxygen Sensor A non-membrane dissolved oxygen sensor for marine applications. The sensor uses a platinum microelectrode and a counter electrode (thus far composed of copper). A measurement potential is applied to the microelectrode relative to a counter electrode, reducing the dissolved oxygen in the water and generating a current through the microelectrode proportional to the number of oxygen molecules at that electrode. The sensor was first used in 2000 and development is ongoing. Early versions of the instrument applied the measurement potential for up to 30 seconds, with sampling starting approximately one second after the potential was applied. The sensor response to oxygen remained almost constant for a given concentration and data could be sampled at frequencies exceeding 1 Hz. To reduce noise generated by sensitivity to flow fluctuations a mesoporous layer was used to increase the surface area of the microelectrode, but this proved unstable and was replaced by a stop-flow system which pumped water in to a very small chamber, with measurements being taken while the water was still. This significantly improved results but the sensor was still affected by small convection currents. The current version of the sensor only applies the measurement potential for a few 10s of milliseconds and data are collected at approximately 1 Hz in an attempt to minimise the effects of convection currents. The latest development is a very small sensor head containing an array of microelectrodes (currently an array of five) that work together. The counter electrode consists of silver or silver chloride. This is currently undergoing trials and is yet to be deployed on a CTD profiler. 2011-07-27

The end of the corer is fitted with a tapered cutter section and a catcher to retain the sample. Sample tubes are fitted with a clear polycarbonate liner with diameter of 63.5mm. To collect a core sample, the corer is lowered down to the seabed on the end of a wire, stopping a set distance above. It is then lowered at a set speed into the sediment to obtain the sample, before being raised to the surface, it is dismantled and the polycarbonate core liner encasing the sample is removed. The weight can vary between 100kg to 1000kg. Depending on the size of the sample tube, the corer is capable of collecting sediments between 1-4 m in length. 2017-11-23

The corer is lowered on a wire to the seabed and a trigger system causes the core barrel to free fall into the sediment to collect samples. The action of the piston reduces internal friction allowing long cores to be collected. Core samples of 90mm and 110mm diameter can be taken. Up to five sections of 5.4 metre-long barrels can be fitted depending on the type of sediment being sampled. 2017-11-23

TOOL1038 Operational Land Image The Operational Land Imager (OLI) is a high resolution optical imager designed for land and vegetation observation. It measures in the visible, near-infrared, and short-wave infrared spectrums over nine spectral bands. The OLI uses long detector arrays (of over 7000 detectors per spectral band) aligned across its focal plane to view across the swath. A four-mirror anastigmatic telescope focuses incident radiation onto the focal plane while providing a 15 degree field of view (FOV). Periodic sampling of the cross-track detectors as the observatory progresses along a ground track forms the multispectral digital images. The detectors are divided into 14 modules arranged in an alternating pattern along the centreline of the focal plane. The spectral differentiation is achieved by interference filters arranged in a butcher-block pattern over the detector arrays in each module. Silicon PIN (SiPIN) detectors collect the data for the visible and near-infrared spectral bands (bands 1 to 4 and 8) while Mercury-Cadmium-Telluride (MgCdTe) detectors are used for the shortwave infrared bands (bands 6, 7, and 9). The OLI has a swath width of 185 km and produces images with a 30 m multi-spectral spatial resolution. The wavelengths of the nine spectral bands are 0.433-0.453 micrometres, 0.450-0.515 micrometres, 0.525-0.600 micrometres, 0.630-0.680 micrometres, 0.845-0.885 micrometres, 1.560-1.660 micrometres, 2.100-2.300 micrometres, 0.500-0.680 micrometres and 1.360-1.390 micrometres. The OLI produced data calibrated to an uncertainty of less than 5 percent in terms of absolute, at-aperture spectral radiance and to an uncertainty of less than 3 percent in terms of top-of-atmosphere spectral reflectance for each of the spectral bands.

TOOL1040 Optical Spectrograph and infrared Imager System The Optical Spectrograph and infrared Imager System (OSIRIS) is a limb-scanning spectrometer. It measures vertical profiles of spectrally dispersed, limb-scattered sunlight from the upper troposphere into the lower mesosphere to produce height profiles of O3 (ozone), NO2 (nitrogen dioxide) and stratospheric aerosols. It operates in the visible, near-infrared and near-ultraviolet spectrums. The OSIRIS instrument is essentially two optical subsystems, suggested by its name: an optical spectrograph (OS) module and an infrared imager (IRI) module. The OS is a grating spectrometer with a CCD (charged coupled device) detector. Vertical profiles of the limb radiance are obtained by taking OS exposures while performing a repetitive vertical scan of the single line-of-sight through selected tangent altitude ranges (10 - 100 km). The IRI is composed of three vertical near infrared co-aligned linear array imagers that capture one-dimensional images of the limb radiance with a tangent altitude resolution of approximately 1 km. The imagers have parallel bore-sights; each one consists of an identical baffling system, lens, narrow-band interference filter, and a one-dimensional linear array of 128 thermo-electrically cooled photodetectors placed in the focal plane of the lens. Approximately 30 photodetector elements at one end of each array are covered with a mask in order to provide a continuous measure of the dark signal in the array. Therefore there are approximately 100 lines of sight from each imager channel that measure simultaneously over 100 vertical kilometres in tangent altitude. OSIRIS (OS) has a spectral range of 280 - 800 nm and a spectral resolution of 1 nm when at an altitude range of 5 -100 km. Each scan takes 40 - 70 seconds. The OS also has a minimum sensitivty of 12 kR per Angstrom per pixel. The IRI captures images of the limb radiance at at 1260, 1270, and 1530 nm and has a sensitivity of 50 kR per band per pixel.

TOOL0016 Ott pneumatic tide gauge The Ott pneumatic gauge derives its measuring signal from the pressure produced in a bubbler system. The pressure is applied to one end of a pivoted beam. On the other side of the pivot is a weight which is moved up and down the beam by an electric motor in order to counter balance the pressure signal. At the far end of the beam are electrical contacts which operate the motor in the correct sense when the beam moves out of balance. The motor is also geared to a double helix shaft with the pen arm attached. The position of the pen is therefore proportional to the applied air pressure. 2009-11-30
TOOL1039 Ozone Monitoring Instrument The Ozone Monitoring Instrument (OMI) is a cross-nadir scanning sounder which follows on from NASA's Total Ozone Mapping Spectrometer (TOMS). OMI is designed to monitor recovery of the ozone layer by measuring different aerosols (smoke, dust, sulfates) and other criteria pollutants such as O3 (ozone), NO2 (nitrogen dioxide), BrO (bromine) and chlorine dioxide (OCLO). The OMI observes Earth's solar backscattered radiation in the visible and ultraviolet spectrums with a wide-field telescope, using hyperspectral imaging in a push-broom mode. This feeds two imaging grating spectrometers, each of which employs a charged coupled device (CCD) detector. Onboard calibration includes a white light source, LEDs, and a multi-surface solar-calibration diffuser. A depolariser removes the polarisation from the backscattered radiation. The OMI has a 13 x 24 km spatial resolution which can be zoomed to 13 x 13 km for detecting and tracking urban-scale pollution sources. The OMI employs three spectral bands, with wavelengths detected in the visible spectrum from 350 - 500 nm (band 1) and wavelengths detected in the ultraviolet spectrum from 270 - 314 nm (band 2) and 306 - 380 nm (band 3). In total there are 1560 channels across the tree bands. The overall spectral resolution of the OMI is from 0.45 -1.0 nm for full width at half maximum (FWHM).

TOOL1041 Phased Array type L-band Synthetic Aperture Radar The Phased Array type L-band Synthetic Aperture Radar (PALSAR) is an active microwave sensor using L-band frequency to achieve high resolution cloud-free, day-and-night land observation, all-weather soil moisture observation and ocean surface features observation. PALSAR can observe in three different modes; fine-resolution mode, a secondary ScanSAR (burst mode SAR) observation mode for monitoring sea-ice and rainforest extent, and Polarimetric mode for receiving simultaneous horizontal and vertical polarisation (multi-polarimetry). PALSAR transmits successive pulses of radio waves to illuminate the target scene, and the echo of each pulse is received and recorded via an array of side-viewing beam-forming antennae. All elements of these arrays receive echos simultaneously in real time so the signals passing through them are individually subjected to controlled shifts of the phases of those signals. Signal processing of the successive recorded radar echoes allows the combining of the recordings from these multiple antenna positions to produce a high-resolution image. PALSAR has a centre frequency of 1270 MHz (L-band). In fine resolution mode, the swath width ranges from 40-70 km and a resolution of 7 - 44 m. In ScanSAR mode, the swath width ranges from 250 350 km with a 100 m multi-look resolution. In polarimetric mode, the swath width ranges from 20 - 65 km with a spatial resolution of 24 - 89 m.

The Poseidon-3 altimeter emits pulses at two frequencies to measure the distance from the satellite to the surface (range). Free electrons in the atmosphere can delay the signal's return, affecting the measurement accuracy. The delay is directly related to the radar frequency, so the difference between the two measurements can be used to determine atmospheric electron content. Poseidon-3 is coupled with Doris/Diode, to improve measurements over coastal areas, inland waters and ice. Poseidon-3 emits pulses at 13.6 and 5.3 GHz in the C band, with pulse duration at 105 microseconds.

TOOL1046 Radar Altimeter The Radar Altimeter (RA) is a nadir-pointing active microwave sensor designed to measure the time return echoes from ocean and ice surfaces. Functioning in one of two operational modes (ocean or ice), the Radar Altimeter provides information on significant wave height, surface wind speed, sea surface elevation which relates to ocean currents, the surface geoid and tides, plus various parameters over sea ice and ice sheets. RA operates by timing the two-way delay for a short duration radio frequency pulse, transmitted vertically downwards. The required level of accuracy in range measurement calls for a pulse compression (chirp) technique. In ocean mode a chirped pulse of 20 microsecond duration is generated with a band width of 330 MHz. For tracking in ice mode an increased dynamic range is used, obtained by reducing the chirp bandwidth by a factor of four to 82.5 MHz, though resulting in a coarser resolution. RA operates in the Ku-band at 13.8 GHz, with an accuracy in range better than 10cm.

TOOL1047 Radar Altimeter 2 Radar Altimeter 2 (RA-2) is a dual-frequency, nadir-pointing, pulse-limited active microwave sensor designed to measure the two-way delay of the radar echo from the Earth's surface. RA-2 also measures the power and the shape of the reflected radar pulses. It's design is based on the heritage of ERS-1 Radar Altimeter (RA). RA-2 transmits frequency modulated pulses (chirp) pulses. This frequency modulation is a coding of the signal which spreads the energy of a short pulse over a longer time interval, thus allowing reduced peak power in the pulse. The transmit pulses, which are generated in the chirp generator (by means of SAW RAC) are amplified by either Ku-band or S-Band amplifiers, depending on the selected transmit frequency. The Ku-band HPA uses a traveling wave tube whilst the S-band transmitter applies the solid state technology. The Ku-band front end electronics (KFEE) or the S-band front end electronics (SFEE) feed the signals to be transmitted to the antenna which is designed as a dual-frequency parabolic antenna. RA-2 operates at 13.575 GHz (Ku-band) and 3.2 GHz (S-Band) and at high precision at less than a nanosecond. It measures the power level and time delay of 128 samples of echoes from ocean, ice, and land surfaces. It is optimised to maintain the leading edge of this echo in the range window.
