Summary The focus of the Naval Postgraduate School's work as part of this collaborative effort with SPAWAR Systems Center, Pacific (Amalia Barrios, PI) and Naval Surface Warfare Center, Dahlgren (Katherine Horgan, PI), is to improving the performance of the Navy Atmospheric Vertical Surface Layer Model (NAVSLaM), developed by the Naval Postgraduate School, in characterizing the evaporation duct in coastal areas. This will lead to improved radar and electromagnetic (EM) system performance predictions for U.S. Navy warfighters when operating in littoral regions. Concurrent in situ meteorological and propagation data collected during an at-sea experiment off the coast of Den Helder, The Netherlands, in September 2014 will be used to evaluate various modified versions of the NAVSLaM model employing different parameterizations, with the goal of developing and validating an improved NAVSLaM model. The impact of employing the improved NAVSLaM model with numerical weather prediction (NWP) model forecasts, such as from the Naval Research Laboratory's Coupled Ocean-Atmosphere Mesoscale Prediction System (COAMPS), will also be evaluated in a coastal area. NPS will also provide the Netherlands Ministry of Defense (MOD) researchers with technical advice on different methodologies of modeling the evaporation duct in a coastal region under the continuing US-Netherlands Coalition Warfare Programs Advanced Refractive Effects Prediction System (AREPS) Project Agreement.
