MISR Level 2 FIRSTLOOK Aerosol parameters V001Entry ID: MIL2ASAF1
Abstract: The MISR Level 2 FIRSTLOOK Aerosol Product contains Aerosol optical depth and particle type, with associated atmospheric data, produced using ancillary inputs from the previous time period.
The MISR Level 2 Aerosol data product contains a variety of information on the
Earth's atmosphere. The aerosol data include troposheric aerosol optical depth on 17.6-km centers, archived with a compositional ... model identifer and retrieval residuals, ancillary data including relative humidity, ozone optical depth, stratospheric aerosol optical depth and retrieval flags.
MISR multi-angle imagery will be used to monitor global and regional trends in
radiatively important optical properties (optical depth, single scattering albedo, and size distribution) and amounts (mass loading) of natural and anthropogenic aerosols, including those arising from industrial and volcanic emissions, slash-and-burn agriculture, and desertification. Coupled with MISR's determinations of top-of-atmosphere and surface albedos, these data will provide a measure of the global aerosol forcing of the shortwave planetary radiation budget.
The MISR instrument consists of nine pushbroom cameras which measure radiance in four spectral bands. Global coverage is achieved in nine days. The cameras are arranged with one camera pointing toward the nadir, four cameras pointing forward and four cameras pointing aftward. It takes 7 minutes for all nine cameras to view the same surface location. The view angles relative to the surface reference ellipsoid, are 0, 26.1, 45.6, 60.0, and 70.5 degrees. The spectral band shapes are nominally Gaussian, centered at 443, 555, 670, and 865 nm.
