This image shows a very much reduced view of the upper midwest as
seen by the NOAA-12 satellite at 13:00 UT 1997 Apr 13 (8:00 am CDT).
A map of this pass shows that the
satellite flew directly over eastern Iowa, the sun was about 17 degrees
above the eastern horizon in this morning view.
Much of the white or yellow bright areas are frozen lakes or snow
cover on the ground. The eastern edge of the image, mostly southeast
and northeast, are covered by clouds. The southwest corner is also
cloud covered.
In the southern half of this image a broad band of snow cover extends from eastern Colorado to Lake Michigan. Northern Kansas has some snow, as does extreme northern Missouri. Nebraska is completely covered.
The northern half of the image shows previous snow cover which has
been melting and adding to the flood waters in the region.
The images on this page were made by combining AVHRR channels 1, 2, and
4 (reversed) as red, green, and blue. This combination shows high cold
clouds as white or blue white and vegetation as green. Snow appears
in shades of pale yellow or blue white depending on thickness and temperature.
The brighter green area in central Oklahoma, extending into southern
Kansas might be winter wheat. These images show many cities and towns,
and a lot of other details. It is worth exploring with a good atlas.
Three sets of more detailed images are available: half size JPEG (starting with the image on this page), full size JPEG, and full size GIF.
