MI3DRDR_2 is the Multi-angle Imaging SpectroRadiometer (MISR) Level 3 Component Global Radiance Regional public Product covering a day version 2. It contains a global summary of the Level 1 and Level 2 radiance parameters of interest averaged over a day and reported on a geographic grid, with a resolution of 0.5 degree by 0.5 degree. Data collection for this product is complete. The data are for distinct regions associated with associated field campaigns.
The MISR instrument consists of nine push-broom cameras that 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 forward, and four aftward. It takes seven 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.
