Atmospheric Ducting Effect in Wireless Communications: Challenges and Opportunities [PDF]
Journal of Communications and Information Networks, 2021 Atmospheric ducting has a significant impact on electromagnetic wave propagation. Radio signals that are trapped and guided by the atmospheric duct can travel a much longer distance over the horizon with lower attenuation since the signal power does not spread isotropically through the atmosphere.

Coastal effects on radar propagation in atmospheric ducting conditions [PDF]
Meteorological Applications, 2006 AbstractTwo models were used to assess the effects of coastal characteristics on radar propagation in ducting conditions in the Persian Gulf. The NCAR/Penn State MM5 model simulated atmospheric conditions at a 5‐km horizontal spatial and hourly temporal resolution on a day on which observations of ducts existed.
