Evaluation of High-Resolution Precipitation Estimates from Satellite Observations
Abstract
During recent years, a number of satellite-derived, globally complete, high resolution precipitation products with a spatial resolution of at least 0.25° and a temporal resolution of at least three-hourly have been developed and produced regularly. These products generally merge geostationary infra-red data and polar- orbiting passive microwave data to take advantage of the high sampling of the infra-red and the superior quality of the microwave, and sometimes use ancillary data such as radar or gauge observations or model output. The Program to Evaluate High Resolution Precipitation Products (PEHRPP) was established by the International Precipitation Working Group to evaluate and inter-compare these datasets at a variety of spatial and temporal resolutions with the intent of guiding dataset developers and informing the user community regarding the error characteristics of these useful products. This presentation will summarize the current state of PEHRPP-related investigations, including the results from the International PEHRPP Workshop held in December 2007.
