NWS Hydrologic Research Lab, R. Fulton Technical Memorandum regards mapping of the WSR-88D (NEXRAD) rainfall estimates onto the HRAP

 

reviewers of this document should also consult the Reed & Maidment article "Coordinate Transformations for using NEXRAD Data in GIS-Based Hydrologic Modeling" in the Journal of Hydrologic Engineering. 1999.4:174-182 for additional understanding of the HRAP and how NEXRAD rainfall estimates can be transformed for use in GIS as well as describing distortions in area (and hence precipitation volume) caused by spherical rather than ellipsoidal projection.
