Efficiency of a global algorithm for retrieving SST from satellite data in a subtropical region Original Research Article

A global split-window algorithm for the retrieval of sea surface temperature from AVHRR has been developed using a radiative transfer code. In order to analyze the performance of the equation obtained which is applied to the Canary Islands zone, we have simulated a set of satellite measurements. The purpose was to classify the errors determined by the global algorithm, depending on the atmospheric situation at each moment. In the final results we give an explanation of the inefficient performance of global algorithm in comparison with a regional algorithm.
