Climate Center). Conversely, it is foreseen that GCIP multidisciplinary studies and data products will provide a high-quality benchmark for the validation of MTPE Earth Observing System observations in the forthcoming TRMM and AM-1 satellite missions. However, MTPE field programs within the Mississippi River basin should be encouraged during the GCIP climate experiment.

U.S. WEATHER RESEARCH PROGRAM

The U.S. Weather Research Program (USWRP) provides a research focus for the ongoing modernization of the National Weather Service. USWRP is attempting to improve the specificity, accuracy, and reliability of whether forecasts using the best possible mix of modern observations, data assimilation, and forecast models. In particular, USWRP's goal is to improve forecasts of high-impact weather for agriculture, construction, defense, energy, transportation, public safety (emergency management), and water resources management, including floods. USWRP is especially concerned with studies related to quantitative precipitation forecasting. These include the measurement, estimation and depiction of water vapor; the representation of convection in forecast models; and the estimation of precipitation amount and type by radar and satellite. USWRP has also begun to consider the control on extreme events by surface effects, including soil-vegetation and canopy. These weather prediction research efforts complement GCIP's regional climate activities. In addition, USWRP's studies related to quantitative precipitation forecasting will help GCIP understand how to make better use of NEXRAD products. USWRP is also beginning to coordinate its activities with the World Weather Research Programme, which is proposed to have formal linkages to GEWEX through the World Meteorological Organization in Geneva. It would be advantageous for the GEWEX and GCIP climate programs to develop links to these national and international weather prediction efforts, especially when expensive field experiments are planned.
