MCD45A1.051 Burned Area Monthly Global 500m (MODIS/051/MCD45A1)

Version V051

The MCD45A1 Burned Area product is a monthly Level-3
gridded 500-meter product, which contains burned area and quality
information. Produced from both the Terra and Aqua MODIS-derived
daily surface reflectance inputs, the algorithm analyzes the
daily surface reflectance dynamics to locate rapid changes, uses
that information to detect the approximate date of burning, and
maps only the spatial extent of recent fires. It provides varied
quality assessment information and a single summary quality assessment
score for each pixel.

The monthly MCD45A1 product is based
on three months of atmospherically- and geometrically-corrected,
cloud-screened daily reflectance data.

burndateApproximate Julian day of burning from eight days before the beginning of the month to eight days after the end of the month, or a code indicating unburned areas, snow, water, or lack of data. Possible values: 0 (unburned), 1-366 (approximate Julian day of burning), 900 (snow or high aerosol), 9998 (internal water bodies), 9999 (external water bodies - seas and oceans), or 10000 (not enough data to perform inversion throughout the period).
ba_qaBurned area pixel detection confidence (1 means most confident while 4 and 5 mean least confident).
npassesNumber of observations that pass the temporal consistency test.
nusedNumber of observations used in the temporal consistency test.
directionDirection in time in which burning was detected (forward, backward or both).
surfacetypeInformation describing the land cover type and properties.
gap_range1Information describing the largest number of consecutive missing/cloudy days (if any) in the time series and the start day of the missing/cloudy period.
gap_range2Information describing the second largest number of consecutive missing/cloudy days (if any) in the time series and the start day of the missing period.
