  Information - NH1.01 Global precipitation measurements and hydro-meteorological extremes.

Event Information
Quantifying fluxes of water among hydrologic reservoirs, and understanding the causes of global water and energy cycle variability are key aspects of improving global climate change predictions and atmospheric warming effects. Precipitation is probably the most important component of a complex mixture of hydrologic cycle parameters (precipitation, evapo-transpiration, soil and canopy wetness, snow, etc.) that govern the daily life of the planet, and is an important element for monitoring the climatic state of water in the earth stores and its variability. Precipitation estimates over large regions are available based on passive microwave observations from earth-orbiting satellite platforms and proxy parameters (cloud-top temperature and cloud particle size) inferred from geo-stationary observations of visible (VIS) and infrared (IR) radiances. The launch of Tropical Rainfall Measuring Mission (TRMM) satellite in 1997 has marked a new era of precipitation measurement research facilitated by the availability of high quality and resolution space-borne radar/radiometer observations. The improved rainfall estimation from combination of TRMM with other satellite measurements has enhanced satellite rainfall applications in hydro-climate research, climate modeling, weather forecasting, and hydrology. Further advances, especially in the prediction of hydro-meteorological extremes, can be achieved with the upcoming Global Precipitation Measurement mission being planned by NASA, NASDA, and European agencies. Contributions are solicited in all areas of global precipitation measurement sciences and applications. Those include papers on (1) cloud dynamics and microphysical processes, (2) remote sensing estimation techniques, (3) ground validation approaches, (4) assimilation of observations into weather forecasting and climate models, and (5) hydrological and risk management applications with special emphasis on the prediction of floods and flash floods, and soil moisture variability. Presentations addressing the issue of uncertainty in precipitation measurement and its propagation in applications are especially welcomed.
