This file contains the MISR Level 3 Global Cloud public Product in netCDF format covering a quarter (seasonal).

Description

MI3QCLDN_002 is the Multi-angle Imaging SpectroRadiometer (MISR) Level 3 Global Cloud public Product in netCDF format covering a quarter version 2 data product. It is a global summary of the Level 1 and Level 2 cloud parameters of interest averaged over a quarter (seasonal) and reported on a geographic grid; it has multiple data layers with varying temporal resolutions of 0.5 degrees by 0.5 degrees and 2.5 degrees by 2.5 degrees resolution.

The seasons are winter (December from the previous year, January and February), spring (March, April, and May), summer (June, July, and August), and fall (September, October, and November). 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 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. 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 successively 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.
