This thesis assesses the performance of the Naval Postgraduate School Aerosol Optical Depth NPS AOD model utilizing very high spatial resolution QuickBird QB satellite data. QuickBird derived AOD results are compared to other satellite and ground based AOD results, specifically, AErosol RObotic NETwork AERONET, MODerate resolution Imaging Spectroradiometer MODIS, Multi-angle Imaging SpectroRadiometer MISR, and Advanced Very High Resolution Radiometer AVHRR. Data is collected around Sir Bu Nuair Island, United Arab Emirates in September 2004 as part of the UAE2 Campaign. Satellite measured radiances are calibrated and due to spatial resolution differences between sensors, modal radiances are calculated for areas matching the highest resolution sensor. The AOD model is based on AVHRR wavelengths hence, the modal satellite measured radiances are linearly extrapolated to the effective wavelengths of AVHRR. Results show application of the NPS AOD model to QuickBird data yields findings that are consistent with other satellite and ground based retrievals. In general, the NPS AOD model works well for nadir and near-nadir view angles, but not for high zenith angles.
