UAH Daily Solar Insolation Page

The following graphics show the daily amount of energy incident on the ground for a given day.  These values are calculated using GOES-9, GOES-10, GOES-12 and METEOSAT-7 visible satellite images for each daylight hour.  The approximate amount of energy reaching the ground is calculated for each image.  This model takes into account the effect of clouds if there are clouds present.  Every night, the images are integrated together to give the estimated total amount of energy reaching the ground from the sun.

These values are based on a model developed by Dr. George Diak (CIMSS) and Dr. John Mecikalski (CIMSS/University of Alabama in Huntsville).

Contact person: Dr. John R. Mecikalski
