MISR is the acronym for Multi-angle Imaging Spectroradiometer. This sensor, equipped with four spectral bands in the visible / near-infrared wavelength range: 0.446, 0.557, 0.672, and 0.866 µm, operates from aboard the EOS-TERRA satellite since 2000. MISR acquires reflectances using nine cameras; one is looking nadir, while of the remaining eight cameras, four are looking into and four against the flight direction of the satellite at fixed view angles with respect to the Earth surface: 26.1, 45.6, 60.0, and 70.5 degrees. By means of its spectral resolution and permanently observing the atmosphere at the given different view angles, a large number of different aerosol and cloud parameters can be retrieved.
A list of the aerosol parameters which ICDC offers is this parameter list (txt-Format).
More information about the data sets can be found on the web pages of the Langley Atmospheric Science Data Center, here: https://asdc.larc.nasa.gov/project/MISR , and in the references.
ICDC offers the monthly globally gridded product at 0.5 degree grid resolution; this gridded product is based on the 2017 re-processing (version v23) and is based on the level-2 product with 4.4 km resolution obtained with the same re-processing.

Most of the MISR data offered here contain as a measure of uncertainty on the standard deviation of all level-2 grid cells used for the computation of the level-3 product. In addition, there are data layers for all parameters providing the count of valid level-2 product values used in the level-3 product in the respective grid cell.
We refer to the documents listed in the references for further information regarding evaluation activities of - mostly - the level-2 products; the qualtiy of these determines the level-3 product quality..
