Abstract

Advanced 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 Advanced Along-Track Scanning Radiometer (AATSR) sea surface temperature values on ESA ENVISAT satellite L3U product. These data are newly introduced product in the third reprocessing of (A)ATSR multimission data.

It is produced by the new ARC L2P processor version 1.2 that also produced the new L2P data. The L3U product is produced through averaging the L2P data onto a regular grid at 30 arcminute resolution. Hence, the L3U product is similar to the AST/METEO product.
