MOD08_M3 V6 is an atmosphere global product that contains monthly 1 x 1 degree grid average values of atmospheric parameters. These parameters are related to atmospheric aerosol particle properties, total ozone burden, atmospheric water vapor, cloud optical and physical properties, and atmospheric stability indices. The product also provides means, standard deviations, QA weighted statistics, log-normal distributions, uncertainty estimates, and statistics for fractions of pixels that satisfy some condition. Below is a subset of the bands, for a complete list see the MOD08 Band List.
