CIMSS provides sectorized VIIRS true-color imagery for each of the five Great Lakes, and for the entire Great Lakes basin at the Direct Broadcast ftp site (ftp://ftp.ssec.wisc.edu/pub/eosdb/j01/viirs/ and ftp://ftp.ssec.wisc.edu/pub/eosdb/npp/viirs for NOAA-20 and Suomi-NPP, respectively). The imagery above shows NOAA-20 images saved from that site and merged together to make an animation (except for 12, 13, 14 November. Mea Culpa) over Lake Erie. Click here to view the animation as an mp4. (Additional animations for the other Great Lakes have also been created:  Lake Ontario in animated gif / mp4) Lake Huron in animated gif / mp4 ; Lake Michigan in animated gif / mp4; Lake Superior in animated gif ; mp4)

The daily views allow a user to view slow changes in the Lake’s circulation — when skies are clear. Such was the case on 8, 9 and 10 November, shown below. A slow anticyclonic motion in the widest part of central Lake Erie is apparent.
