| Definition | An eight-band whiskbroom scanning radiometer designed for land and vegetation observation. The instrument consists of a primary mirror sweeping across-track to produce image scans, and a scan line corrector (SLC) mirror assembly sweeping forward-to-back along-track, to compensate for the forward motion of the satellite during integration time. A panchromatic channel covers the wavelength range (0.50 - 0.90) um, at a spatial resolution of 15 m and 12000 pixel per line; six-narrow band channels in the visible/near-infrared/short-wave infrared (VIS/NIR/SWIR) span wavelength ranges (0.45 - 0.52) um, (0.53 - 0.61), (0.63 - 0.69) um, (0.78 - 0.90) um, (1.55 - 1.75) um, (2.09 - 2.35) um, at a spatial resolution of 30m and 6000 pixel per line; a thermal infrared (TIR) channel covers the band (10.4 - 12.5) um, at a spatial resolution of 60 m and 3000 pixel per line. The swath width is 185 km. Flown on Landsat-7. http://www.wmo-sat.info/oscar/instruments/view/136 | ||
