Steven Delwart(1)

(1) ESA-ESTEC, Keplerlaan1, 2201AG, Noordwijk, Netherlands


The radiometric calibration results from the first 5 years of operation of the MEdium Resolution Imaging Spectrometer (MERIS) on-board ENVISAT will be presented. Radiometric calibration methodology using the on-board diffusers will be discussed and compared to the results from different vicarious calibration techniques. Finally, the vicarious adjustment introduced for ocean colour retrieval will be presented
