Ongoing improvements of our numerical weather prediction (NWP) models by the research community, combined with rapid changes in military operations and DOD information assurance policies, demand a streamlined transition process under a strict configuration management system. These transitions are often complicated by the necessity to integrate the NWP models into complicated information technology (IT) systems and operational run control schedules.
This paper will detail two recent NWP transitions which illustrate some of the challenges and solutions associated with the systems integration. The 1st example discusses the use of the NOAH Land Surface Model within the Coupled Ocean/Atmosphere Mesoscale Prediction System (COAMPS) and the analyses surrounding the choice of initial conditions. The 2nd example outlines the addition of radar data assimilation to COAMPS under a new Real-time Environmental Assessment runtime and post-processing system.
