Fire Burnt Area

Fire Burnt Area

This model shows the Fire Burnt Area using the MODIS data. Burned areas are characterized by deposits of charcoal and ash, removal of vegetation, and alteration of the vegetation structure. The MODIS burned area mapping algorithm takes advantage of these spectral, temporal, and structural changes.
It detects the approximate date of burning at a spatial resolution of 500 m by locating the occurrence of rapid changes in daily surface reflectance time series data. The algorithm maps the spatial extent of recent fires and not of fires that occurred in previous seasons or years.

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, and uses that information to detect the approximate date of burning, mapping the spatial extent of recent fires.
