Java applet developed by Tom Whittaker, CIMSS / SSEC

This loop of GOES-8 3.9 micrometer shortwave InfraRed (IR) imagery shows that the region of elongated bands over northcentral and northeastern Iowa (associated with blowing snow and ground blizzard conditions across that region on 21 December 2000) were not composed of supercooled cloud droplets, which reflect incoming solar radiation and appear warmer (yellow enhancement) on this channel. A region of supercooled cloud was moving southward into northern Iowa, behind the blowing snow bands.
