The Terra and Aqua combined MCD64A1 Version 6 Burned Area data product is
a monthly, global gridded 500m product containing per-pixel burned-area
and quality information. The MCD64A1 burned-area mapping approach employs
500m MODIS Surface Reflectance imagery coupled with 1km MODIS active
fire observations. The algorithm uses a burn sensitive vegetation index (VI)
to create dynamic thresholds that are applied to the composite data.
The VI is derived from MODIS shortwave infrared atmospherically corrected
surface reflectance bands 5 and 7 with a measure of temporal texture.
The algorithm identifies the date of burn for the 500m grid cells within
each individual MODIS tile. The date is encoded in a single data layer as
the ordinal day of the calendar year on which the burn occurred, with
values assigned to unburned land pixels and additional special values
reserved for missing data and water grid cells.
Burn day of year. Possible values: 0 (unburned), 1-366
(approximate Julian day of burning).

Bitmask for QA
Bit 0: Land/water
0: Water grid cell
1: Land grid cell
Bit 1: Valid data flag. A value of 1 indicates that there was
sufficient valid data in the reflectance time series for the grid
cell to be processed. (NB Water grid cells will always have this bit
clear.)
0: Insufficient valid data
1: Sufficient valid data
Bit 2: Shortened mapping period. This flag indicates that the
period of reliable mapping does not encompass the full one-month
product period, i.e., burns could not be reliably mapped over the
full calendar month.
0: Mapping period not shortened
1: Mapping period shortened
Bit 3: Grid cell was relabeled during the contextual relabeling
phase of the algorithm.
0: Grid cell was not relabeled
1: Grid cell was relabeled
Bit 4: Spare bit
0: N/A
Bits 5-7: Special condition code reserved for unburned grid cells.
This code provides an explanation for any grid cells that were
summarily classified as unburned by the detection algorithm due to
special circumstances.
0: None or not applicable (i.e., burned, unmapped, or water grid cell).
1: Valid observations spaced too sparsely in time.
2: Too few training observations or insufficient spectral
separability between burned and unburned classes.
3: Apparent burn date at limits of time series.
4: Apparent water contamination.
5: Persistent hot spot.
6: Reserved for future use.
7: Reserved for future use.
