Product Summary
The Level-3 MODIS Atmosphere Monthly Global Product
contains roughly 800 statistical datasets that are derived from the
Level-3 MODIS Atmosphere Daily Global Product.
It should be noted that the content of this product is identical to the Eight-Day Global Product,
only the temporal scale is different.
There are two MODIS Monthly Global data product files:
MOD08_M3, containing data collected from the Terra platform; and
MYD08_M3, containing data collected from the Aqua platform.
Statistics are sorted into 1x1 degree cells on an equal-angle grid
that spans a (calendar) monthly interval and then summarized over the globe.
Computed Statistics
A range of statistical summaries are computed, depending on the parameter being considered.
Statistics for a given measurement might include:
- Simple (mean, minimum, maximum, standard deviation) statistics
- Parameters of normal and log-normal distributions
- Fraction of pixels that satisfy some condition (e.g. cloudy, clear)
- Histograms of the quantity within each grid box
- Histograms of the confidence placed in each measurement
- Histograms and/or regressions derived from comparing one science parameter
to another, statistics may be computed for a subset that satisfies some condition
