Ice in Lake Superior

A sequence of Terra and Aqua MODIS true color images from the SSEC MODIS Direct Broadcast site (above) reveal that widespread ice that had formed in parts of Lake Superior during the 08 March09 March10 March 2008 period. There are 2 images from each of those 3 days, with the Terra and Aqua images on each day separated by less than 2 hours — and even in that short time, you can see some movement of the ice features due to surface winds blowing across the lake and shifting the ice fields (plus the change in wind direction from day to day moved the ice features in different directions). Temperatures across northeastern Minnesota, northern Wisconsin, and the Upper Peninsula of Michigan had been fairly cold during the first week of March 2008, with minimum temperatures of -33º F (-36º C) at Embarrass, Minnesota and -26º F (-32º C) at Upson, Wisconsin on 07 March, and -31º F (-35º C) at Herman, Michigan on 08 March. While somewhat impressive, the ice coverage over Lake Superior did not match that seen back in February/March 2003.

  1. Thanks for the excellent link to the MODIS pictures of Lake Superior. It also shows the lakes in NE MN, so I can watch for Ice Out now.
    Very cool.

    Do you know how or where I can find similar daily photo’s of minnesota lakes further west than in this picture? I am not understanding how to get data out of the MODIS system…

    THANKS!

    Your best source for viewing daily MODIS true color images over northern MN would probably be our “SSEC MODIS Today” site:

    You also have the option of viewing the imagery using Google Earth, which would allow you to tailor your particular image display location and overlay towns and highways…
