Evaporation Duct Refractivity Profile

This paper discusses the principles of evaporation duct refractivity profile estimation using bulk meteorological measurements. Four prevailing models among a number of developed ones were examined. Simulation results were compared with direct refractometric measurements. The sensitivity of the models to the measurement accuracy of the meteorological parameters was analyzed. As result LKB and RSHMU models can be recommended for farther use in oversea radiowave propagation calculation
