A comparison of the MODIS SST product with the RTG_SST<\/a><\/strong> High Resolution model analysis (below)<\/em><\/strong> serves to illustrate how satellite data can add value in situations where even high-resolution models struggle to accurately depict some of the smaller-scale SST structures that were present in the Gulf of Mexico. For example, the RTG_SST_HR analysis placed the axis of warmest SST values over the eastern<\/em> portion of the Loop Current, where MODIS SST values were in fact a few degrees F cooler than they were over the warmer western<\/em> portion. The highest MODIS SST values in the western part of the Loop Current were around 80\u00ba F<\/strong> (darker red colors),<\/em> which were about 4-5\u00ba F higher than what was indicated in that area by the RTG_SST_HR analysis.<\/p>\n

Three days earlier, AVHRR SST values in the southern portion of the Loop Current were as warm as 83\u00ba F (below)<\/em><\/strong> — however, brisk surface winds associated with the passage of a strong cold front helped to lower the SST values a bit, due to mixing and upwelling of slightly cooler water from below the surface.<\/p>\n
