    ATSR Gridded Surface Temperature

    Last update: 22 June 2017

    The Gridded Surface Temperature (GST) Product is the Level 2 full resolution geophysical product. The product contains gridded sea-surface temperature images using both nadir and dual view retrieval algorithms. The product includes pixel latitude/longitude positions, X/Y offset and the results of the cloud-clearing/land-flagging.

    It contains a single measurement data set the content of which is switchable, that is to say, the content of each pixel field will depend on the surface type. Specifically, the contents of the data fields will depend on the setting of the forward and nadir cloud flags and the land flag.

    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.
