Along-Track Scanning Radiometer (AATSR) mission was funded jointly by the UK Department of Energy and Climate Change External Link (DECC) and the Australian Department of Innovation, Industry, Science and Research External Link (DIISR).

This dataset contains the Along-Track Scanning Radiometer on ESA ERS-1 satellite (ATSR-1) L2P sea surface temperature product. These data are full resolution data with dual-view Sea Surface Temperature (SST) values. Version 3.0 of this dataset have been produced with the ARC L2P processor version 1.2, which replaces the ARC SST processor. The processor applies its own algorithm to generate SST data from the Level 1B Data. This method differs from that used to produce the Gridded Surface Temperature (GST) products. This product also includes the ATSR Saharan Dust index (ASDI) and the clear-sky probability estimated by the ARC cloud detection algorithm.
