| dc.description.abstract | Using the NOAA-14 1-km Advanced Very High Resolution Radiometer (AVHRR) and the Geostationary Operational Environmental Satellite (GOES-8) imager data, smoke aerosol optical thickness (τ) is retrieved over land during the Smoke, Clouds and Radiation-Brazil (SCAR-B) experiment in Brazil during August-September 1995. The satellite-retrieved τ values are then compared against ground-based sunphotometer derived τ values from the Aerosol Robotic Network (AERONET) program. Both the AVHRR and GOES 8 retrieved τ values are in excellent agreement with the AERONET derived τ values with linear correlation coefficients of 0.93. A single scattering albedo of 0.90 (at 0.67 µm) provides the best fit between the measured and retrieved values. The sensitivity of the retrieved τ to assumed surface albedo and aerosol single scattering albedo are also examined. A simple thresholding algorithm is used to separate smoke from other features over land from GOES-8 satellite imagery and regional maps of τ are provided. Our results show that the aerosol properties used in this paper are adequate to characterize biomass-burning aerosols and can be used in studies that model the role of biomass burning on regional climate. | |
