Ducting Conditions During CASPER-West Field Campaign

The Coupled Air-Sea Processes and Electromagnetic ducting Research (CASPER) project involved two field campaigns. The most recent field study, CASPER-West, occurred during 27 September–26 October 2017 offshore of Pt. Mugu, California. The most significant ducting conditions observed during this field campaign included evaporation ducts and surface-based ducts. However, most of the evaporation ducts are also topped by elevated duct layers at several hundred meters above the surface. This paper provides an overview of the CASPER-West measurements and the observed ducting conditions from multiple platforms in CASPER-West.
