| Definition | The Thermal And Near-infrared Sensor for Carbon Observation - Cloud and Aerosol Imager (TANSO-CAI) is one of two instruments that the Thermal And Near-infrared Sensor for Carbon Observation (TANSO) is composed of. It is a radiometer designed to measure aerosol spatial distribution and cloud coverage in the visible, ultraviolet and shortwave infrared spectrums. This information is primarily used to correct the effects of clouds and aerosols on the spectra obtained from the primary TANSO instrument, Thermal And Near-infrared Sensor for Carbon Observation - Fourier Transform Spectrometer (TANSO-FTS). TANSO-CAI has a continuous spatial coverage, wider field of view, and higher spatial resolution than TANSO-FTS in order to detect aerosol spatial distribution and cloud coverage. Using the multispectral bands, the spectral characteristics of the aerosol scattering can be retrieved together with optical thickness. In addition, the UV-band range observations provide the aerosol data over land. With the FTS spectra, imager data, and the retrieval algorithm to remove cloud and aerosol contamination, the column density of the gases can be retrieved with an accuracy of 1%. The TANSO-CAI instrument operates within four sepctral bands in the following wavelength ranges: 0.370-0.390 micrometres (band1); 0.664-0.684 micrometres (band 2); 0.860-0.880 micrometres (band 3); 1.56-1.65 micrometres (band 4). The instrument has a spatial resolution of 0.5 km at nadir for bands 1-3, and 1.5 km at band 4. https://earth.esa.int/web/guest/data-access/latest-data-products/-/article/gosat-cai-l1-l2-l3-full-archive-and-new-products | |
