Description:
From the NOAA 15 minute precipitation file for the U.S., data was selected for 128 stations covering a 17 year period and the probability of simultaneous rainfall at several stations was calculated. We assumed that the chosen stations were located in separate beams of a multi-beam communications satellite with shared fade mitigation resources. In order to estimate the demands made on these resources, we determined the number of stations at which rainfall rates exceeded 10 to 40 mm/hr. We found a 1 percent probability that at least 5 of the 128 stations have rain at or over 10 mm/hr in any 15 minute interval. Rain at 2 stations was found to correlate over distances less than about 600 miles.
