MISR Level 2 Firstlook Products

Firstlook Products

The MISR Level 2 Products are geophysical measurements derived from the Level 1B2 data. The Top-of-Atmosphere (TOA)/Cloud Products contain measurements of TOA bidirectional reflectance factors, stereoscopically-derived cloud and land (reflecting level) elevation, cloud fraction, cloud texture, and other related parameters. The Level 2 Aerosol/Surface Product includes a range of parameters such as tropospheric aerosol optical depth; aerosol composition and size; surface directional reflectance factors and bi-hemispherical reflectance; and other related parameters. The Level 2 products are in swaths, each derived from a single MISR orbit, where the imagery is 380 km wide and approximately 20,000 km long.

First Look: Initial data processed with apriori boundary conditions. Once actual conditions are obtained (about 3 months), the data are reprocessed to final product.
