    Visible Channel Long Term Drift Analysis Using Desert Targets

    Visible Channel Long Term Drift Analysis Using Desert Targets. The stability of AATSR visible channel calibrations have been measured using data from stable desert targets. The calibration drift rates obtained from the time-series are less than 3.5% per year and comparable to those measured for ATSR-2. Application of the drift correction to AATSR L1B images is discussed.

    Validation Report following the 3rd MERIS data reprocessing

    This document prepared by the MERIS Quality Working Group (QWG) corresponds to the Validation Report following the 3rd MERIS data reprocessing. It aims at qualifying and quantifying the accuracy of the MERIS L2 products generated with the version 8.0 of MERIS Ground Segment prototype (MEGS), delivered to the whole community through the ODESA software (http://earth.eo.esa.int/odesa/). It is equivalent to version 6.0 of the Instrument Processing Facilities (IPF) at ESRIN.
