Abstract
The Along-Track Scanning Radiometer (ATSR) series of instruments provides the means to obtain precise measurements of sea surface temperature (SST) (± 0.3 K, 1-sigma limit). With the launch of the Advanced ATSR (AATSR) in March 2002, this will lead to a 15 + year dataset that can be used to study long-term global climate change. In this paper, we present validation results from more than one year of comparisons between the AATSR 1 km SST product and in situ measurements obtained from the Marine Atmospheric Emitted Radiance Interferometer (M-AERI) over the Caribbean. These results indicate that the product is performing within specification over this geographical area at night, with some issues still to be resolved for day time SST retrievals. We also present evidence that the presence of atmospheric aerosol is affecting the quality of the AATSR SSTs, particularly during the day, and a method of filtering out 'contaminated' pixels based on the results of this experiment.
