Burned Area - Fire Frequency

Parameter 

Burned Area - Fire Frequency

Represented classes

Number of years where a fire is observed (2000-2020)

Fire Frequency range: 1 – 21 years 

Description 

This layer shows the number of years for which there has been a fire detected in the period 2000-2020. Forest fires will normally have only one recorded fire while cropland or grasslands can have yearly fires. The darker pixels show areas where the yearly frequency of fires is higher. 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

Description 

The Terra and Aqua combined MCD64A1 Version 6 Burned Area data product is a monthly, global gridded 500 m product containing per-pixel burned-area and quality information. The MCD64A1 burned-area mapping approach employs 500 m MODIS Surface Reflectance imagery coupled with 1 km 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 500 m 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.
