Evaporation duct assessment from meteorological buoys [PDF]
Radio Science, 2002 The evaporation duct over the sea is usually assessed using bulk meteorological measurements. This paper investigates the utility of meteorological buoys as a source for these bulk measurements and compares evaporation duct assessments using two buoys in southern California waters separated by 128 km.

Experimental Analysis of Atmospheric Ducts and Navigation Radar Over-the-Horizon Detection
Remote Sensing, 2022 Since the height of sea detection radar antenna and ship targets is relatively low, it is generally believed that its over-the-horizon detection is mainly caused by the evaporation duct at sea.
