The Fourth International Precipitation Working Group Workshop

Quantitative precipitation estimates (QPEs) on a global scale are only possible from satellite observations or through numerical weather prediction (NWP) model analyses. Satellite observations, available from a range of sensors that have different spectral, spatial, and temporal characteristics, may be used to generate precipitation products. Techniques used to retrieve rainfall from such observations vary, ranging from relatively simple empirical relationships to physical retrieval techniques. The resulting products are used across many applications such as hydrology, water resource management, and for monitoring temporal and regional changes in precipitation related to climate variability. The International Precipitation Working Group (IPWG) provides a focus for scientists from across the world to advance the measurements of precipitation from space and subsequently exploit the derived precipitation datasets.
