Satellite-based precipitation measurements are critical for a wide range of applications, such as terrestrial hydrology, water resources, climate change, agriculture and natural hazards. However, their usefulness is ultimately determined by the uncertainties in these measurements (Fig. 1). This project focuses on quantifying the uncertainties, attributed to both systematic and random errors, and on tracking down the error sources in the upstream satellite sensors.
NASA's precipitation ESDRs are produced in two levels: level 2 and 3. Level-2 products contain rainfall measurements directly derived from satellite sensors at their footprint scales, while level-3 products are typically merged data from multiple level-2 products and other sensors and mapped into a uniform space and time grid.
This project is sponsored by the National Aeronautics and Space Administration (NASA)
under the ESDR-ERR Program (NASA Contact: Martha E. Maiden).
