Abstract: We have examined NOAA-5 satellite-derived sea-surface temperature data in the Fiji region for a one-year period starting September 1977. Time series analysis revealed that the satellite data has spatial and temporal resolutions characterized by a coherence time of about 4 days and a coherence length of 850 km. A systematic difference T between ship and satellite readings was found to correlate significantly with the surface temperature itself, with latitude, and with vapor pressure. Several possible models to explain the behavior of triangle T are introduced. We conclude that while surface emissivity variations, incomplete cloud decontamination, and cooling across the air-sea interface may all be contributory factors, the bulk of the discrepancy between ship and satellite arises from insufficient corrections being made for atmospher attenuation.
