Monitoring of satellite precipitation estimates through the IPWG validation studies

Abstract

A major activity of the International Precipitation Working Group (IPWG) is the verification, validation and intercomparison of precipitation products to enable product developers and users to continually monitor and assess the performance of the available products. This activity has developed an ongoing validation program, comparing surface reference datasets and satellite precipitation products to better inform product developers and the user community. This section gives an overview of the IPWG validation program. IPWG validation aims to improve satellite precipitation products, focusing upon statistical analysis over regions with existing reference data at moderate temporal/spatial resolutions.
