Abstract

The integrity of a free-space optical communications link can be directly correlated to the atmospheric conditions through which the link is made. The link may become degraded due to optical turbulence and absorptive/ scattering losses resulting in reduced signal strength and may result in failure to close a link. It is important to analyze atmospheric conditions in order to predict and mitigate these performance losses. The goal of this work is to characterize local atmospheric conditions in a coastal environment over a 560 m terrestrial optical range. Local atmospheric and weather data were gathered utilizing several data collection instruments including an anemometer, a scintillometer, and a weather station hub. The data analyzed in this work were temperature and path averaged scintillation index (C_n²). Experimental data collections and analysis of monthly weather conditions are presented with C_n² values ranging from 10^-15 to 10^-12 (m^-2/3) and temperature values ranging from 8 to 31 (℃).
