Session 13 CASPER Special Session: Coastal Air–Sea Interaction Affecting Electromagnetic Wave Propagation. Part I

Thursday, 16 January 2020: 1:30 PM-3:00 PM
158 (Boston Convention and Exhibition Center)
Host: 18th Symposium on the Coastal Environment

The Coupled Air-Sea Processes and Electromagnetic ducting Research (CASPER) is a five-year multiple disciplinary research program aimed at improving the understanding and prediction of environmental conditions resulting in ducting of electromagnetic waves (EM), mostly associated with the atmospheric surface layer or the boundary layer capping inversion. Two intensive field campaigns and multiple efforts of numerical modeling studies utilizing large eddy simulation (LES) and mesoscale models, as well as EM propagation models, have been conducted during the CAPSER period. This session provides the opportunity to present recent advances from the CASPER efforts in understanding air-sea interaction processes, coastal internal boundary layer development, coastal upper ocean processes, and EM ducting in the measured and modeled atmospheric environment. The session presentations will especially address major scientific gaps in accurately capturing and representing the vertical gradients of wind and thermodynamic properties and small-scale turbulence structure in the marine environment.
