Minimize AATSR Level 3

AATSR Level 3 Demonstration Products

Sea surface temperature (SST) is one of the key measures made in studying the global climate system, essential in detecting climate change. Sea surface temperature levels are symptomatic of heat exchange between the ocean and atmosphere, and thus are an invaluable input in global climate research. 

"Studying climate models show us we need at least 15 years' worth of data to differentiate a definite global temperature increase from the normal variability of climate," explained Professor Llewellyn-Jones from Leceister University. "Preliminary analysis of existing results does indicate a general upward trend, but we will be more certain with more time and more data." 

Envisat/AATSR and its predecessors ERS-1/ATSR-1 and ERS-2/ATSR-2 are about to complete 15 years of Sea Surface Temperature measurements with the accuracy required for climate research. In anticipation and as a demonstration, global SST Level 3 products from AATSR from September 2002 to April 2004 have been generated at two spatial resolutions, 10 arcminutes and 30 arcminutes.
