Aerosol Optical Depth Retrieval With AVIRIS Data: A Test of Tafkaa

Abstract

Using solar wavelength radiance data obtained from the airborne AVIRIS instrument, during the LEO experiment, an analysis of aerosol optical depth (AOD) was completed using Tafkaa - a program developed by the Naval Research Laboratory (NRL). The objective of the analysis was to compare Tafkaa-retrieved AOD with AOD retrieved from SeaWiFS, and ground-based sun photometers. The intent of the study was to test enhanced AOD analysis using the hyperspectral coverage provided by AVIRIS. Comparisons between AOD retrieved by Tafkaa provided results consistent with SeaWiFS AOD retrieval and the AOD determined by ground-based sunphotometers in regions with minimal sediment and sun glint. A reliable sun glint mask was produced and applied to remove the effects of sun glint in the AVIRIS data.
