What this study adds:
This study investigates the Arkansas-Red Basin River Forecast Center’s P3 radar precipitation estimator accuracy with select Oklahoma Mesonet gauge locations. The data collected comes from the NEXRAD radars located within ARBFC’s forecast area as well as rainfall measurements recorded by the Oklahoma Mesonet stations. Radar estimation errors were analyzed from a temporal and spatial standpoint to determine if errors developed specific trends in estimation accuracy. Greater radar estimation accuracy was observed at locations close to radar sites and at locations that were climatologically wetter. The fall season was also shown to have the smallest margin of radar estimation errors.
