| Resumo | Sea surface temperature (SST)data obtained from several sources are used in this work to investigate the discrepancies between in situ measurements and satellite etimations of SST in the Southwestern Atlantic Ocean (SWA). The in situ data were obtained for the period between March 1993 and July 1994 from ships of pportunity and drifting buoys crossing the study area. High resolution satellite data were obtained from the AVHRR (Advanced Very High Resolution Radiometer)and ATSR (Along Track Scanning Radiometer)sensors for the same period and area of study. Match-ups between in situ and satellite SSTs were performed, resulting high regression coefficients (r = 0.9)between SSTs from ships of opportunity and AVHRR SSTs. The regressions between buoy and AVHRR SSTs presented coefficients of about 0.8. Temperature difference (Delta;T)between the in situ and AVHRR data indicated that the NOAA algorithms overestimated the atmospheric attenuation occurring in the SWA in the study period. Unexpectedly, Delta;Ts were higher between buoy and AVHRR data than between ships of pportunity and AVHRR data. In the first case DeltaT was about 1.5oC whereas in the later case Delta;T was about 0.5oC. This result is probably caused by the tendency of the drifters to concentrate in regions of higher horizontal thermal gradients, where the buoys are not generally able to sample SSTs across the front. Analysing the spatial behaviour of the Delta;Ts, as measured between AVHRR and ATSR images, it is noticed that the higher values are related to the positions of the frontal systems, along the buoy tracks. The very active nature of the advection processes occurring in very small periods of time are pointed out as the possible causes for the higher Delta;T values being particularly distributed in the frontal regions. Knowing that drifting buoys that are used in the majority of the validation programmes (especially the NOAA ones)can present the predictable tendency of concentrating in regions of strong thermal gradients at the sea surface, their temperature measurements would inevitably be subject to mismatching with satellite data because of the lateral motions of the fronts. This effect is definitely stronger in the western boundary currents and in regions of convergence, e.g. Brazil-Malvinas Confluence. |
