MODIS Terra and Aqua Direct Broadcast Burned Area Monthly L3 Global 500m 2017

The MODIS Terra and Aqua MCD64A1 Version 6.1 product provides a global monthly burned area dataset at 500 m spatial resolution with per-pixel burn and quality information. The product is generated using MODIS Surface Reflectance imagery at 500 m resolution combined with 1 km MODIS active fire observations. The algorithm applies a burn-sensitive vegetation index derived from atmospherically corrected MODIS shortwave infrared reflectance bands 5 and 7 along with temporal texture analysis to detect burned areas. The dataset identifies the burn date for each 500 m grid cell within a MODIS tile, encoded as the ordinal day of the calendar year when the burn occurred, with additional values representing unburned land, water, or missing data. The product includes layers for Burn Date, Burn Date Uncertainty, Quality Assurance, and the First and Last Day of reliable change detection within the year.
