Аннотация:The paper discusses the results of the recovery of the sea surface temperature (SST) in a large-scale hydrological test area. Data from the NOAA AVHRR radiometer (APT mode) and measurements of the surface temperature by a sensor towed by an RV, by an "STD' sensor and by drifting "LOBAN TM' buoys were used. The paper describes the data measurement and processing methods. Maps of the spatial distributions of the SST are compared. A numerical estimate of the accuracy of the recovery of the SST field from satellite data is given.
