Description

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.

Name Min Max Description
burndate 0 10000

Approximate 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_qa

Burned area pixel detection confidence (1 means most confident while 4 and 5 mean least confident).

npasses 1 255

Number of observations that pass the temporal consistency test.

nused 1 255

Number of observations used in the temporal consistency test.

direction

Direction in time in which burning was detected (forward, backward or both).

surfacetype

Information describing the land cover type and properties.

gap_range1

Information 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_range2

Information describing the second largest number of consecutive missing/cloudy days (if any) in the time series and the start day of the missing period.
