MISR Level 3 FIRSTLOOK Global Cloud public Product in netCDF covering a day V002

Metadata Updated: September 19, 2025

MI3DCDNF_002 is the Multi-angle Imaging SpectroRadiometer (MISR) Level 3 FIRSTLOOK Global Cloud public Product in netCDF covering a day version 2. It contains the public MISR Level 3 FIRSTLOOK Global Cloud public product in netCDF format covering a day. It is a global summary of the Level 1 and Level 2 cloud parameters of interest averaged over a day and reported on a geographic grid. It has multiple data layers, with varying temporal resolutions of 0.5 degrees by 0.5 degrees and granules of 2.5 degrees by 2.5 degrees. Data collection for this product is ongoing.FIRSTLOOK processing uses the new time dependence of the Atmospheric and Surface Climatology (TASC) from the same month/previous year. The TASC data set now contains snow-ice and ocean surface wind speed values that are updated monthly. Therefore, these data sets cannot be generated until the end of the month. Products generated are distinguished by the presence of FIRSTLOOK in the file names.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 an instrument designed to view Earth with cameras 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.This file contains the public MISR Level 3 FIRSTLOOK Global Cloud public Product in netCDF format covering a day.
