Figure 3:

Cumulative distribution of the active fire area globally and for the seven biomes for 2008. The x axis shows the number of voxels sorted in ascending order by active fire area and the y axis shows the normalized cumulative active fire area. The active fire areas are calculated using the 2008 MODIS active fire detections (Section 3.3). The vertical line indicates the 20^th quantile of the active fire area cumulative distibution; 80% of the active fire area is detected in just 1% to 11% of the voxels, depending on the biome.
