Abstract:

LONG-TERM GOAL. Our long term goal is to contribute to the development and evaluation of an operational evaporation duct model for use in microwave propagation prediction. OBJECTIVES. We have three main objectives. Our first objective is to develop a metric, involving one or more parameters, to replace evaporation duct height as a fundamental basis for comparison and evaluation of evaporation duct models. Our second objective is to use experimental data to evaluate various LKBbased where LKB refers to Liu et al 1979 evaporation duct models e.g., the BYC model described in Babin et al 1997, the NRL-Monterey Model, etc. to determine the best models using the objective criterion from the first objective. Our third objective is to perform a sensitivity study to evaluate the possible effects of issues raised during the Naval Postgraduate School Evaporation Duct Workshops on the LKB approach to evaporation duct models.
