VIIRS True-Color Imagery over the Clear Great Lakes
Clear skies over the upper Midwest allowed all 3 JPSS Satellites — Suomi NPP, NOAA-20 and NOAA-21 — to obtain excellent views of the Great Lakes on 11 April 2023. The Great Lakes are largely ice-free (with the exception of a few bays in northern Green Bay, over northern Lake Superior, and over northern Lake Huron). (Here are two images from 7 March for comparison). The CIMSS Direct Broadcast site includes imagery for each of the five Great Lakes (here’s Lake Erie, for example, from NOAA-20 at 1846 UTC on 11 April, via this direct link to this directory, valid for about a week); the animation below shows Suomi NPP, NOAA-20 and NOAA-21 images of the Great Lakes from the CIMSS Direct Broadcast website (link) with 5 images between 1705 and 1911 UTC. Multiple JPSS Satellites means that time animations are easily created.
VIIRS imagery is also available at the VIIRS Today Site and at the CIMSS VIIRS Imagery Viewer. True-Color imagery is also available via an LDM feed from CIMSS.
