The ENVISAT AATSR continues the ATSR-1 and ATSR-2 mission data sets of precise sea surface temperature (SST), thereby ensuring the production of a 10 year near-continuous data set from the ERS-1 and ERS-2 missions at the levels of accuracy of 0.3 K or better for climate research. AATSR was launched on board the Envisat satellite on 1st March 2002.

More Information (under review)

AATSR has the same signal channels and embodies exactly the same viewing principle as ATSR-2. These are: thermal channels at 3.7, 10.8, and 12 microns wavelength; and reflected visible/near infrared channels at 0.555, 0.659, 0.865, and 1.61 microns wavelength. Like its predecessors, ATSR-1 and ATSR-2, AATSR has on-board calibration systems for the thermal channels, using two black bodies, viewed every scan, and for the visible channel a sample of solar radiation scattered from a diffuser plate is viewed once per orbit. Unlike ATSR-2 it maintains full digitisation of all channels all the time and has no limited-data-rate operating modes.
