COAMPS Refractivity Forecast Evaluation Using LATPROP- UWB Propagation Loss Data

Abstract

Lower Atmospheric Propagation Ultra Wide Band (LATPROP-UWB) system is deployed during Coupled Air-Sea Processes and Electromagnetic Ducting Research (CASPER) East campaign to measure range-dependent propagation loss for 2–40 GHz. Couple Ocean/Atmosphere Mesoscale Prediction System (COAMPS) is used to obtain refractivity forecasts during CASPER East. Range-dependent forecast refractivity profiles are used with a parabolic wave equation code to get simulated propagation loss. The simulated and measured propagation loss are compared to compute COAMPS forecasting accuracy.
