Detection of sea surface temperature (SST) using AVHRR data in the Gulf of Finland

Presents the detection of sea surface temperature (SST) in the Gulf of Finland using AVHRR data. AVHRR imagery is evaluated as a main data source for monitoring SST as a measure of upwelling dynamics. Sea surface effects (SSE), however, cause a temperature difference between the sea surface skin and water below the surface. Therefore, SSE are taken into account as one of the major error factors in the SST estimation.
