MISR Level 3 Component Global Radiance Product covering a day V004

This file contains the MISR Level 3 Component Global Radiance Product covering a day.

MIL3DRD_004 is the Multi-angle Imaging SpectroRadiometer (MISR) Level 3 Component Global Radiance Product covering a day version 4. It contains a statistical summary of spectral top-of-atmosphere Bidirectional Reflectance Factors for various sub-region classifications and a statistical overview of spectral expansive albedos for several sky classifications. This data product is a global summary of relevant Level 1 radiance parameters, averaged over a day and reported on a geographic grid with a resolution of 0.5 degrees by 0.5 degrees. Data collection for this product is ongoing.

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 exact 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.

MISR is designed to view Earth with cameras pointed in 9 different directions. As the instrument flies overhead, each piece of Earth's surface below is successfully imaged by all nine cameras in 4 wavelengths (blue, green, red, and near-infrared). The goal of MISR is to improve our understanding of the effects of sunlight on Earth and distinguish different types of clouds, particles, and surfaces. Specifically, MISR monitors the monthly, seasonal, and long-term trends in three areas: 1) amount and type of atmospheric particles (aerosols), including those formed by natural sources and by human activities; 2) amounts, types, and heights of clouds, and 3) distribution of land surface cover, including vegetation canopy structure.
