Precipitation and Average Recurrence Interval Grids

Precipitation and Average Return Intervals coverage across the state were developed by MetStorm®, a precipitation analysis system, using innovative algorithms to blend 857 daily and hourly gauge stations provided by Synoptic and the South Carolina State Climate Office, dual-pol radar estimated precipitation provided by Weather Decision Technologies, Inc, and satellite precipitation estimates from NOAA. The maps were produced by MetStat, Inc. for the State Climate Office.
