MOD08_M3 V6.1 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.

 

MOD08_M3 V6.1是一个大气全球产品,包含大气参数的每月1×1度网格平均值。这些参数与大气气溶胶颗粒特性、臭氧总负荷、大气水汽、云的光学和物理特性以及大气稳定性指数有关。该产品还提供平均值、标准偏差、QA加权统计、对数正态分布、不确定性估计,以及满足某些条件的像素比例的统计。下面是一个波段的子集,完整的列表见MOD08波段列表。
