Karl track on Gulf of Mexico SST image of 12 September (333 Kb) This image
represents the average composite sea surface temperature (SST) derived from
NOAA satellite AVHRR data over the 7 days ending 12 September 2010. The
averaging is done to remove clouds. The streaking artifacts are due to problems with the NOAA-17 satellite data. The temperature scale for SST is
24C to 34C. The track of Karl is overlaid on this image.
