Between 2012 and 2025, VIIRS detected fire in 888 km² of Töv at least once. In an average year it detected fire in 66 km², ranking 7th of 22 regions of Mongolia.
Year by year
Detected area per year, km². Area of 0.01° cells with at least one detection in the year.
The busiest year was 2017, with 512 km² detected; the quietest was 2016, with 5.0 km². The 2021–2025 average is 64% lower than the 2012–2016 average.
Through the year
Share of all fire-days 2012–2025 by month. A fire-day is one cell with a detection on one day.
May, June and July together hold 79% of the fire-days in the record. The single busiest day was 15 July 2017, with detections in 254 cells.
Ground that burns again
Of the 888 km² with at least one detection, 0.6% had detections in three or more different years.

- 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.
