Abstract

The PROTURB model, developed by the Battlefield Environment Directorate of Army Research Laboratory, calculates an estimate of optical turbulence strength and its effects on visible and IR imaging and laser system performance. The PROTURB model was earlier compared to data obtained from the REBAL 92 field test held in Bushland, Texas, and data supplied by the Army Test and Evaluation Command Ft. Belvoir Meteorological Team. Recent PROTURB updates included modifying the radiative flux portion of the energy balance model. Here we present a new comparison using data from three locations that differ greatly in meteorological conditions, and moderate climatic conditions. There also exists a considerable difference in site characteristics such as ground conditions and vegetation. We discuss the data collection and reduction effort, and show how this data compares with PROTURB predictions.
