Estimation of precipitation derived from space-borne and ground-based measurements is critical to understanding how the water cycle changes in a warming climate for a host of societal applications such as monitoring water resources, flood and landslide warning, and drought monitoring. Retrieval methods and models deal with challenges arising from the inherent variability of precipitation at all scales involving diverse physical processes. Advancements in quantitative precipitation estimation have occurred in the last decade through the synergy of instruments providing improvements in terms of accuracy, coverage and resolution. Two major projects to be discussed are the Global Precipitation Measurement mission led by NASA and JAXA for the description of precipitation at the global scale, and the Multi-Radar Multi-Sensor initiative from the NOAA/National Severe Storms Laboratory for quantitative precipitation estimation at high spatial and temporal resolution over the conterminous U.S. Both projects face similar challenges, and while some answers target retrievals at the hydrometeor scale, it is now recognized that uncertainty estimates of ground and satellite precipitation estimation are necessary to realize their full potential. Implications for hydrologic applications will be discussed as well.

For accommodations based on disability, or more details, please call 325-6561. All visitors without NOAA or University of Oklahoma identification must register at the registration desk on arrival. Visitor parking is available for all University visitors. However, faculty/staff/students must have a current multi-purpose parking permit. Additional parking is available at the Lloyd Noble Center (LNC) for those individuals who do not have a parking permit. You do not need a permit to park in one of 1,200 spaces reserved for CART bus riders, although you must ride the CART shuttle to park in the reserved area. This area is on the north central side of the Lloyd Noble Center. Elsewhere at the LNC, permits are required.
