prototype high-altitude numerical weather prediction (NWP) and data
assimilation (DA) system has recently been developed based on the operational
Navy Global Environmental Model (NAVGEM) that can generate global synoptic
meteorological analyses every 6 hours from the ground to the lower
thermosphere (~100 km altitude). In addition to assimilating operational
meteorological observations in the 0-50 km altitude range, this high-altitude
version of NAVGEM can also assimilate temperature and constituent
measurements throughout the stratosphere and mesosphere obtained from
satellite-based instruments. This presentation will discuss changes in the
forecast model introduced to improve model accuracy and thus minimize bias at
high altitudes. Results from this new system show how it can be used to (1)
provide improved initial conditions for stratosphere-resolving NWP and
climate models; and (2) investigate dynamical coupling between the
troposphere, stratosphere, and mesosphere. A challenge facing high-altitude
NWP efforts is the scarcity of operational satellite observations above 50
km. The importance of these types of observations for planned development of
unified ground-to-space forecast systems will also be discussed.</span><span style="font-size:11pt;font-family:"Arial","sans-serif""></span></p>
