%X Satellite estimates of ocean/atmosphere heat fluxes were compared with surface measurements taken at John Brewer Reef (18°38'S, 147°E) located 80 km NNE of Townsville, Australia. For a 45 week period all the components of the surface heat fluxes : net radiation, sensible and latent heat fluxes, were estimated from surface observations and averaged on a weekly basis. Concurrent satellite observations in the vicinity of John Brewer Reef consisted of GMS visible reflectance data, NOAA-9 soundings of temperature and humidity, and sea surface temperatures derived from a blend of ship observations and NOAA-9 data. Wind estimates were derived from the Darwin Tropical Analysis. All satellite data were tested for their ability to reproduce surface heat fluxes. The rms differences (measured versus modeled) between the weekly averaged values of net radiation, the turbulent heat flux (sensible plus latent) and the total ocean/atmosphere heat flux were 16 Wm-2, 45 Wm-2 and 48 Wm-2 respectively. Averaged over the 45 week period, a mean difference of 9 Wm-2 (measured-modeled) was obtained for the total ocean-atmosphere heat exchange. (Résumé d'auteur)
