A real-time meteorological data assimilation and forecast system to support army RDT&E

摘要

This paper describes a system in which meteorological observations are used in near real time with a full-physics mesoscale meteorological model to obtain an optimum analysis of current conditions and short-term forecast of future conditions. This real-time four-dimensional data assimilation (RTFDDA) system is intended to: (1) improve the information available to support real-time goo-go test conduct decisions; and (2) provide high-resolution gridded analyses of atmospheric conditions to support post-test forensic analyses and virtual testing. The prototype RT-FDDA system is operational at Dugway Proving Ground, Dugway, Utah, and similar systems will be deployed at the major Developmental Test Command test centers during Fiscal Years 2002 and 2003.
