Abstract
The first generic and climatological aerosol retrievals using AirMISR data are presented. Observations in a cloud-free region over Monterey Bay on July 29, 1999, yield complementary generic and climatological results. According to the generic retrieval, the cross-section-weighted, column-mean aerosol properties are: x. = 0.1 0.05, with a preference for values on the low side of the range, r a = 0.45 0.15, with a preference for the 0.30 to 0.40 sub-range, n i 0.003, with 0.0 as the most likely value. These properties corresponding to a "large spherical" column-average particle, such as sea salt. The climatological retrieval identifies a Maritime air mass, having a total aerosol optical depth about 0.1, and fractional optical depths for sea salt of 50% in MISR Band 2, and 40% for the sulfate + carbonaceous (medium, spherical) components, to an accuracy of about 15%. These results, in good agreement with nearby surface-based and aircraft observations, represent an early step toward the goal of adding spatial detail and information about temporal variability to the global aerosol climatology with MISR multi-angle data.
