The Mississippi River floodplain in northwestern Mississippi and eastern Arkansas, often referred to as the Mississippi Delta, is unique in currently having 3 sources of precipitation observations : 1) multi-sensor precipitation estimates from the National Weather Service (NWS) NEXRAD network; 2) surface observations from NWS recording stations; and 3) surface observations from U.S. Department of Agriculture (USDA) Soil Climate Analysis Network (SCAN) recording stations. For meteorological and climatological precipitation research, quantitatively defining the biases associated with available precipitation data sources is critical in selecting which source to use for a given application. Results of this research indicate that the multi-sensor data are in best agreement with surface observations during the cool season. Additionally, overall bias values among the data sources decrease after 2002, at which point the remotely sensed and surface-based estimates show improved agreement
