Viewing-angle geometry for the multi-angle camera (MISR)
What it measures. The sun and viewing angles for the MISR instrument's nine differently-pointed cameras, measured at Earth's reference surface.
How it's made. Produced from the multi-angle MISR camera system on NASA's Terra satellite, which images each spot on the ground from nine directions.
How & where you'd use it. A geometry helper layer used to correctly interpret MISR's multi-angle imagery rather than a standalone science product.

Official description
Multi-angle Imaging SpectroRadiometer (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 fate of sunlight in Earth's environment 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. MISR Geometric Parameters V002 contains the Geometric Parameters which measure the sun and view angles at the reference ellipsoid
