Radar Rainfall Data: Temporal and Spatial Characteristics
Publication: Radar Rainfall Data Estimation and Use (MOP 139)
Abstract
Common formats for gridded radar rainfall data include ESRI Shapefile, Arc/Info ASCII Grid, Gridded NetCDF, and others, and commercially produced gridded rainfall data sets are available in various temporal and spatial resolutions. The data are typically available in geographic information system-compatible formats that are easily processed for input to hydrologic models. Of special note are two standardized grid systems in common use by U.S. government agencies: The Hydrologic Rainfall Analysis Project grid used by the U.S. National Weather Service and the Standard Hydrologic Grid used by the U.S. Army Corps of Engineers. Radar rainfall data have various purposes. Some uses include real-time hydrologic monitoring, flood forecasting, flood hazard and disaster management, probable maximum precipitation estimation, extreme storm analysis, and many others. Accurate estimation of volumetric watershed outflow is a key objective in hydrologic analysis.
