Quality Assurance - Cloud Mask Statistics

Last Update: September 29, 2006

Cloud Mask Statistics are presented as a series of plots, listed below. Each data point represents the daily average of the statistic in question, read directly from the product metadata for each MOD35_L2 (or MYD35_L2) Collection 5 granule. The sample is taken from day-only granules, night-only granules, granules containing both day and night (circumpolar and seasonally dependent), or all available granules for each data day. Plots will open in a new window.

Note that all percentages are with respect to the total number of pixels possible; if SuccessfulRetrievalPct is less than 100% then other percentages will be reduced accordingly.
