GOES-16 (GOES-East) “Red” Visible (0.64 µm) images (above) revealed an increasing amount of ice coverage within the nearshore waters of southern Lake Michigan on 07 February 2021 — this was due to a recent influx of arctic air across the Upper Midwest and western Great Lakes.

A sequence of VIIRS True Color RGB and False Color RGB images from Suomi-NPP and NOAA-20 (below) provided 375-meter resolution views of the lake ice.

The MIRS Sea Ice Concentration product derived from Suomi-NPP ATMS data (below) depicted maximum values of 60-63% (lighter green), which was fairly consistent with the Ice Concentration analysis from GLERL.

The Suomi-NPP VIIRS Sea Surface Temperature product (below) revealed values of 34-39ºF along the leading edge of widespread lake effect cloud bands that were producing snowfall in Lower Michigan.

A 250-meter resolution Aqua MODIS True Color RGB image of the ice at 1917 UTC (from the MODIS Today site) is shown below.

Finally, an overpass of Landsat-8 offered a 30-meter resolution view of a portion of the lake ice near Chicago, as visualized using RealEarth (below).
