Evaluation of Aerosol Size Distribution Models

摘要

The Navy aerosol model is important for prediction of atmospheric optical (visible and infrared) properties over the ocean, and hence for predicting the performance of FLIR systems. The use of satellite measurements to measure the aerosol size distribution in the marine boundary layer has been demonstrated by Science Applications International Corporation (SAIC) and provides the possibility of using satellite measurements to make predictions of FLIR performance. In this study, measurements of the aerosol optical thickness using different techniques were compared, with the objective of investigating the feasibility of using satellite data for FLIR performance prediction. SAIC provided satellite and sunphotometer ground truth measurements, and Naval Ocean Systems Center (NOSC) provided aircraft and infrared sky radiance measurements of aerosol properties. This report describes the SAIC measurements. Keywords: Modeling; Forward looking infrared. (kt/jes)
