AATSR is a follow-on to theAlong-Track Scanning Radiometer (ATSR) flown on European Remote Sensing(ERS) ERS-1 and ERS-2 spacecraft. The AATSR provided high-precision seasurface temperature measurements and bi-directional measurements of landsurface in 10 channels: 0.470, 0.550, 0.670, 0.870, 1.240, 1.610, 3.750,4.0, 10.85, and 12.0 micrometers. The AATSR gave a FOV of 500 meters in aswath of 500 km for channels up to 1.6 micrometers and 1 km FOV forchannels above 1.6 micrometers.
