GOES  1-km visible imagery

Northern Alaska

Robert Rabin1



This web page provides near real-time imagery for northern Alaska and surrounding areas. The background images linked in table below are from the visible and infrared channels of the NOAA geostationary satellite GOES-17 (western satellite).  Since the GOES satellite is in orbit above the equator (in order to be "geostationary"),  the viewing angle at high latitudes such as Northern Alaska is quite skewed and exhibits degraded resolution. For this reason, the images appear distorted near the northwestern edge of these images.  The apparent offset of clouds from their true location above the ground, parallax, is also a significant problem.  A parallax correction has been applied to the images using the cloud top temperature from band 13 (10.3 microns) and a standard atmosphere temperature profile.  The images are updated at 10-20 minutes intervals.  Note that visible images are available 24 hours daily during the polar summer at these high latitudes.

HTML5 based applications used for interactive animations were developed by Tom Whittaker of the Space Science and Engineering Center  SSEC, University of Wisconsin-Madison.
