    The Gridded Brightness Temperature/Reflectance (GBTR) product contains top of atmosphere (TOA) brightness temperature (BT) values for the infra-red channels and reflectance values for the visible channels. Values for each channel and for the nadir and forward views occupy separate measurement data sets. Additional MDS contain cloud and land/sea flags and confidence flags for each image pixel.

    The 3rd reprocessing of ATSR data has been performed; the processing updates that have been put in place and the expected scientific improvements are outlined in full in the User Note for the Third ERS ATSR Reprocessing.
