In this paper we present results from the first few months of AATSR data. ESA's near-real time Meteo product consists of channel brightness temperatures and a retrieved skin SST spatially averaged to 1/6° resolution. This product is obtained in near-real time at the Met Office, UK, where a skin SST retrieval and conversion to nominal bulk SST are performed. Initial validation of the new SST data includes comparisons against collocated buoy observations and an independent climate SST analysis. Our results confirm the reliability of the instrument and the benefit of including models for the ocean skin effect and diurnal thermocline in the Met Office processing system. A further comparison of SSTs derived from the ATSR-series against those from the TRMM Microwave Imager reveals some discrepancies, for which reasons will be explored.
