Regional validation of AVHRR-derived surface temperature of the Northern Adriatic Sea

Relatively successful global performance of a particular SST algorithm can be misleading, concealing potentially large regional differences. We have therefore undertaken performance testing of globally derived SST coefficients in a local, geographically limited environment of the northern Adriatic. The in situ temperature data available for validation have come from two sources: Project Jadran, and Project ADRICOSM. The comparisons have been limited to the NOAA-16 and NOAA-17 AVHRR sensors and the MCSST and NLSST algorithms. The obtained results suggest that significant biases can exist in global-coefficient estimates, which local validation can ameliorate. Soon to be available set of buoy SST measurements, together with wider choice of algorithms (PFSST in particular), is expected to provide further quantita-tive evidence of the regional character of the Adriatic remotely sensed SST
