A dust and deposition module has been added to the CSU Regional Atmospheric Modeling System (RAMS). The new scheme utilizes a global map of potential sources and parameterizes emissions based on model wind speed and soil moisture. This study focuses on the testing of the new scheme, with emphasis on its ability to accurately model the spatial extent of dust as well as the column optical thickness and surface visibility.

A computer simulation has been developed to optimize the use of the aircraft platform for the measurement of short wave irradiances. This model simulates the measurement of radiative fluxes in order to determine the approximate sample sizes required under various conditions of cloudiness.
