The daily Suomi National Polar-Orbiting Partnership (Suomi NPP) NASA Visible
Infrared Imaging Radiometer Suite (VIIRS) Burned Area (VNP64A1) Version 1
data product is a monthly, global gridded 500m product containing per-pixel
burned area and quality information. The VNP64 burned area mapping approach
employs 750m VIIRS imagery coupled with 750m VIIRS active fire
observations.
VIIRS bands that are both sensitive and insensitive to biomass burning are
used to detect changes caused by fire and to differentiate them from other
types of change.
Ordinal day of burn (1-366) for each 500-m grid cell.
Burn_Date_Uncertainty
%
Estimated uncertainty in date of burn, in days. Unburned, unmapped,
and water grid cells are masked out.
QA
Quality Assurance Indicators
Bitmask for QA
Bit 0: land/water state
0: water grid cell
1: land grid cell
Bit 1: Valid data flag (0 = false, 1 = true). A value of 1 indicates
that there was sufficient valid data in the reflectance time
series for the grid cell to be processed.
0: false
1: true
Bit 2: Shortened mapping period (0 = false, 1 = true). This flag
indicates that the period of reliable mapping does not encompass
the full one-month product period.
0: false
1: true
Bit 3: Grid cell was relabeled during the contextual relabeling phase
of the algorithm (0 = false, 1 = true).
0: false
1: true
Bit 4: Spare bit set to 0
0: Spare bit
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: burned, unmapped, or water grid cells
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
First_Day
First day of the year of reliable change detection
Last_Day
Last day of the year of reliable change detection
