Abstract
The lessons learned from the post-launch testing of the radiometric performance of legacy sensors, GOES, MODIS and VIIRS are reviewed. The focus is on the post-launch radiometric tests carried over an extended period on orbit after successful completion of the initial engineering beta tests on the sensor performance. The best practice guide lines for on orbit characterization and full validation are derived based on this review for the future multichannel optical sensors in JPSS and GOES-R series. Field campaigns using legacy inter-comparisons with calibrated sensors and utilizing new technological developments such as near surface unmanned aerial vehicles (UAVs) for ground truth measurements for calibration/validation will also be discussed. The goal is to achieve SI traceable low radiometric uncertainty and maintain it through the sensor life time on orbit.
