Otto track on Atlantic Ocean SST image of 29 September (254 Kb) This image
represents the average composite sea surface temperature (SST) derived from
NOAA satellite AVHRR data over the 7 days ending 29 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
22C to 32C. The track of Otto is overlaid on this image.
