Overview

STAR/NESDIS generates a suite of precipitation and water vapor products to support NWS operations. The routine validation of these products is critical to evaluate their performance over various regions, seasons and varying synoptic conditions. The primary objective of the validation system is to provide feedback to algorithm developers and one-stop validation recourse to the end-users. The validation system will also assist in identifying the best attributes of the existing retrieval algorithms which will help in the development of future or ‘Next Generation’ precipitation algorithms.

This website disseminates the results of swath-based, monthly and seasonal validation of NOAA (and partner institutions) precipitation products over the Continental United States [CONUS].
