The Spatial and Temporal Variability of the Arctic Atmospheric Boundary Layer and Its Effect on Electromagnetic (EM) Propagation.

Abstract

Gradients of temperature, pressure and moisture affect the propagation of electromagnetic (EM) waves. Navy systems which are dependent on EM propagation can be either enhanced or degraded due to atmospheric conditions which affect atmospheric refractive index profiles. The Navy's model for predicting the refractive index is the Integrated Refractive Effects Prediction System (IREPS) version 2.2, developed by the Naval Ocean Systems Center (NOSC). Atmospheric parameters of temperature, vapor pressure and relative humidity - with relative humidity being the most critical - are used by IREPS to predict the atmospheric refractivity. Keywords: Atmospheric refractivity, Theses, Performance, Horizontally homogeneous atmosphere, Refractive index.
