Between December 2001 and February 2002, NOAA-AVHRR images were obtained twice a day for the region between 30-40S and 70-80W. Within the cloud free areas, sea surface temperature was calculated according to standard split window algorithms. The geo-referenced horizontal resolution for each SST-pixel resulted in 2 km, in east-west and north-south direction. All pairs of images were analyzed with respect to advective surface velocity by means of Maximum Cross-Correlation. Maximum Cross-Correlations exceeding the predetermined significance level of cross correlation were accepted. From all pairs of comparison monthly advective velocity maps (and SST maps) were constructed and separated in a coastal and offshore band. Coastal upwelling was observed along the... |
