A HIGH RESOLUTION SEA SURFACE TEMPERATURE FIELD DERIVED FROM AVHRR INFRARED WINDOW RADIATION MEASUREMENTS
Abstract:
A procedure of deriving high resolution sea surface temperature field from digital AVHRR/HRPT data is described in this paper. For the purpose of reducing the proccesing time, only the reflectivity threshold of near infrared channel is used for selecting data over clear area of ocean, and W. L. Smith single window channel sea surface temperature retrieval method is used for atmospheric attenuation correction for the area of Beihai Bay and Yellow Sea during the cold half of year. Comparing with other measurements the resuet is quite satisfactory.
