The radiometric gains of the AATSR visible to shortwave-infrared channels are calibrated using an on-board solar diffuser. The on-board calibration is supported by vicarious techniques such as comparisons over stable desert targets to establish relative biases in the radiometric calibrations of AATSR and other optical sensors and also to determine the long-term drifts. The authors present the results of comparisons over the Dome-C site in Antarctica, analysis of dark water measurements and multi-platform inter-comparisons. The data and the lessons learned from the calibration monitoring are being fed into the Sentinel-3 calibration planning.
