Objectives: For this study, we are:

• Acquiring sun photometer data using a ground-based instrument as well as the Airborne Tracking Sun Photometer on the C-130. Deriving aerosol optical depths as a function of wave length and submit them to BORIS.
• Using the spectral aerosol optical depths to derive aerosol and size distributions coincident with important BOREAS remote sensing data sets and using the size distributions to calculate aerosol optical properties such as phase functions and single scattering albedos necessary for our atmospheric correction model.
• Incorporating a model of contribution of skylight into our atmospheric correction model to enable calculation of surface reflectances from our surface radiances.
• Extending our atmospheric correction model to data collected by the Advanced Solid-state Array Spectroradiometer (ASAS), incorporating an approximate Rayleigh multiple scattering correction, and provide a detailed evaluation of the results.
• Processing the important remote sensing data sets for BOREAS from the Thematic Mapper (TM), the TM Simulator, System Probatoire de la Terre (SPOT), and ASAS.
