CASPER Research: Toward Improving Similarity Theories for Marine Surface Layer
Abstract
A research program on Electromagnetic (EM) wave propagation in the coastal Marine Atmospheric Boundary Layer (MABL) is proposed, which is to be conducted collaboratively with the NPS research program entitled “Coupled Air-Sea Processes and EM Ducting Research” (CASPER). The objective is to characterize and model MABL as an EM propagation environment. The emphases will be on spatial heterogeneities, nonstationarity and surface wave/swell effects, all of which contravene the underlying assumptions of Monin-Obukhov Similarity Theory (MOST) used in coupled EM-propagation and environmental forecasting models. We will participate in two major field experiments and precursor monitoring efforts to be conducted in Duck, North Carolina, (CASPER-East) and Southern California (CASPER-West). These campaigns are expected to capture EM ducting along the developing internal boundary layers over inhomogeneous regions near the Gulf Stream, evaporative ducts, and near the MABL top under coastal influence. We will employ an array of instrumentation complementary to that of NPS. Measurements will include spatial and temporal atmospheric boundary-layer growth, profiles of atmospheric and oceanic turbulence and Infra Red imaging. Based on the data and theoretical analyses, MOST will be revisited to include the effects of horizontal homogeneity and non-stationarity. The collaboration with NPS and Navy Laboratory partners will help transition research results to Navy s operational environmental forecasting and EM propagation prediction models.
