    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.

    The Status of the SCIAMACHY Active Thermal Control (ATC)

    The Active Thermal Control System (ATC) is providing thermal stability to SCIAMACHY's optical bench module (OBM). Over the past 10 years in-orbit mission lifetime the ATC has proven extremely reliable. Although regular monitoring has revealed some degradation ??? less than what was predicted before launch ??? only a single adjustment was necessary so far to keep the OBM temperature within the specified limit. The ATC adjustment occurred in October 2008 in orbit 34643 [RD1 with referencing RD3-RD6].

    Sea Ice Thematic Data Product [ALT_TDP_SI]

    This is the Sea Ice Thematic Data Product (TDP) V1 resulting from the ESA FDR4ALT project and containing the sea ice related geophysical parameters, along with associated uncertainties: snow depth, radar and sea-ice freeboard, sea ice thickness and concentration. The collection covers data for the ERS-1, ERS-2 and Envisat missions, and bases on Level 1 data coming from previous reprocessing (ERS REAPER and the Envisat V3.0) but taking into account the improvements made at Level 0/Level 1 in the frame of FDR4ALT (ALT FDR). The Sea Ice TDP provides data from the northern or southern hemisphere in two files corresponding to the Arctic and Antarctic regions respectively for the winter periods only, i.e., October to June for the Arctic, and May to November for the Antarctic. For many aspects, the Sea Ice TDP is very innovative: First time series of sea-ice thickness estimates for ERS Homogeneous calibration, allowing the first Arctic radar freeboard time series from ERS-1 (1991) to CryoSat-2 (2021) Uncertainties estimated along-track with a bottom-up approach based on dominant sources ERS pulse blurring error corrected using literature procedure [Peacock, 2004] The FDR4ALT products are available in NetCDF format. Free standard tools for reading NetCDF data can be used. Information for expert altimetry users is also available in a dedicated NetCDF group within the products. Please consult the FDR4ALT Product User Guide before using the data. The FDR4ALT datasets represent the new reference data for the ERS/Envisat altimetry missions, superseding any previous mission data. Users are strongly encouraged to make use of these datasets for optimal results.
