Overview

STAR/NESDIS, NOAA partner agencies, and partner institutions routinely generate a suite of precipitation products to support wide range of users and applications. The validation of these products is critical to evaluate their performance over various regions, seasons and synoptic conditions. With the primary objective to provide feedback to algorithm developers and one-stop validation recourse to the end-users, NPreciSe provides an easy to access assessment of precipitation products against the US radar network. The validation system assists in identifying the best attributes of the existing retrieval algorithms to help with the development of next generation precipitation algorithms.

This website disseminates the results of swath-based, monthly, and seasonal validation of NOAA, its partner agencies, and partner institutions' precipitation products over the Continental United States (CONUS). Near real-time and archived validation is available for following precipitation products:

• CPC MORPHing technique-2 (CMORPH2)
• Self-Calibrating Multivariate Precipitation Retrieval (SCaMPR)
• Global Satellite Mapping of Precipitation (GSMaP)
• Integrated Multi-satellitE Retrievals for GPM (IMERG)
• Precipitation Estimation from Remotely Sensed Information using Artificial Neural Networks (PERSIANN)
• Microwave Integrated Retrieval System (MIRS)
• NOAA-19, NOAA-20, NOAA-21, Suomi-NPP, GPM, F17, F18, MetOp-B, MetOp-C
• Goddard Profiling (GPROF)
• AMSR2
• Blended Rain Rate
• Snowfall Rate (SFR)
• NOAA-19, NOAA-20, Suomi-NPP, GPM, F16, F17, F18, MetOp-B, MetOp-C
• Ensemble Tropical Rainfall Potential (eTRaP)
