Abstract
Project Summary: This project addresses critical issues regarding the effects of low-level cloud/fog on the operational performance of high energy laser (HEL) weapons. This topic represents a large knowledge gap in operating the HEL weapons that inevitably goes through the atmosphere that is often filled with water hygrometers. This research included three parts: instrument development, field measurements, and data analyses. A fog microphysics sensor was modified to fit the application of measuring from a stationary platform and was integrated into a trailer-based laboratory for aerosol and fog sampling. For data collection, we made continuous measurements in two locations in the Monterey Bay area, one at a farm field at the coastline and one further inland over mostly concrete surface. These measurements include both meteorological data as well as propagation data. Data analyses focused on the observed scintillation and attenuation. The amount of optical energy attenuation through the fog layer and the role of scintillation in foggy conditions are being analyzed as part of the thesis work of Captain Zachary Daniels who will graduate in March 2019.
