Retrieval of sea surface temperature from NOAA-AVHRR data - some results

A. Narendranath, M.V. Rao, T.Ch.M. Rao, N.E. Daniel


The NOAA-AVHRR data recorded at the Indian Earth Station are processed for the retrieval of Sea Surface Temperature (SST) by using thermal infra-red channels 4 and 5. The pseudo coloured SST weekly composited imagery for the 5 to 11 May, 1988 with 1 degree C interval are presented. The satellite derived SSTs fairly matched, with those of sea truth observations, with an RMS deviation of 0.57. It is found that the warmer temperatures were present over the western and central parts of the Arabian Sea. The application aspects of satellite derived SSTs are discussed.
