Comparisons of Sea-Surface Temperature Obtained from Ship and Satellite Data.

Abstract

Sea-surface-temperatures (SST) obtained by thermosalinograph on five cruises during the period 23 September 1982 to 30 January 1983 in waters east and north-east of the Australian coastline are compared graphically with SST obtained from three sources of satellite data, GOSSTCOMP charts (Global Operational Sea Surface Temperature Computation), NWS charts (National Weather Service), and GMS (Geostationary Meteorological Satellite) tables. The data is plotted as temperatures versus cumulative ship distance travelled. For these cruises, fronts and features were seldom discernible in the satellite data but broad scale average trends were well shown. GOSSTCOMP was found to be the most reliable temperature indicator, often closely following the graph of highly smoothed ship temperature. NWS often tended to follow peak temperatures while GMS often overestimated SST by more than 3 C. Estimates are given on the usefulness of absolute values of satellite SST in real-time analyses.
