- How these figures are madeDetected area, cells, and the single-satellite record.
Detected area counts every 0.01° cell with at least one VIIRS detection, so a small fire counts as a whole cell and a fire missed by cloud or between passes is absent. Borders: Natural Earth 1:10m. 2012 begins on 20 January.
