The sea surface temperature, SST of Sabah coastal area under clear sky conditions was investigated. Automatic Picture Transmission, APT thermal infrared data from National Oceanic Atmospheric Administration, NOAA satellite of Advanced Very High Resolution Radiometer, AVHRR was used. The APT data was obtained in real-time mode at Ground Receiving Station, GRS in Universiti Malaysia Sabah, UMS. An image processing approach and Planck distribution function method were used to convert the grey-level digital numbers of the APT imagery into radiance values. These data were then converted to 10-bit digital number data of High Resolution Picture Transmission, HRPT images for calibration purposes. Geometric correction was applied with ground control point for APT data. A single channel method together with radiosonde data has been used for the atmospheric and emissivity corrections. The satellite sensor SST was compared with in-situ measurements taken from ships at sea. The results from the SST obtained from APT data give 2.6 degrees C to 2.7 degrees C lower than in-situ data.
