MISR Level 2 FIRSTLOOK TOA/Cloud Albedo parameters V001Entry ID: MIL2TCAF1
Abstract: The MISR Level 2 FIRSTLOOK TOA/Cloud Albedo Product contains local, restrictive, and expansive albedo, with associated data, produced using ancillary inputs from the previous time period.
The MISR Level 2 TOA/Cloud Albedo data product contains top-of-atmosphere (TOA) radiation and cloud information, including Reflecting Level Reference Altitude (RLRA), local albedo and bidirectional reflectance ... factors, referenced to the RLRA, view obscuration information, and texture indices, regional science classifiers, and coarse resolution restrictive and expansive albedos. The RLRA corresponds to the main reflecting layer, which will typically be the tops of bright clouds, or under atmospheric conditions corresponding to clear skies or thin cloud, it will be located at the surface.
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.
