Sea Surface Temperature
|Date of Launch:|
|ERS-1 - 17 July 1991
ERS-2 - 21 April 1995
|ERS-1 ended on March 2000 and ERS-2 September 2011|
|782 to 785 km|
|Near-circular, polar, Sun-synchronous|
The L2P product contains full resolution dual-view Sea Surface Temperature (SST) values. These SST use the ARC SST retrieval and cloud screening which differ from the methods used to produce the Gridded Surface Temperature (ATS_NR__2P) products. In addition to SST, the L2P products contain the ATSR Saharan Dust Index (ASDI) and the clear-sky probability estimated by the ARC cloud detection algorithm.
The L2P processor also generates L3U products; these are the L2P products averaged onto a regular grid at 0.1 degree resolution (they are therefore similar to the AR / Meteo Envisat-format products).
The L2P and L3U products are provided in NetCDF-4 format following GHRSST Data Specifications (GDS) v2.
The L2P/L3U archive has been reprocessed with a new processor based upon the ARC SST; the changes are outlined in full in the L2P Reprocessing User Note.
