Sampling Spatial-Temporal Variability of Electromagnetic Propagation in CASPER-West

The Coupled Air-Sea Processes and Electromagnetic ducting Research (CASPER) is a multidisciplinary research initiative aimed at quantifying electromagnetic (EM) ducting and the associated atmospheric processes. The project involved two field campaigns on both coasts of the US. Coordinated measurements among research vessels/platforms and at the shore were made in both field campaigns resulting in a large amount of data for both the atmospheric environment and EM propagation. This paper presents a general overview of the second field campaign, CASPER-West and the ducting conditions encountered during the field campaign. Examples of the measured propagation are also given.
