MISR Geometric Parameters subset for the ARCTAS region V002

ATSMIGEO_002 is the Multi-angle Imaging SpectroRadiometer (MISR) Geometric Parameters subset for the ARCTAS region version 2. It measures the sun and view angles at the reference ellipsoid. MISR is designed to view Earth with cameras in 9 different directions. As the instrument flies overhead, all nine cameras successfully imaged each piece of Earth's surface below in 4 wavelengths (blue, green, red, and near-infrared). MISR aims 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.
