Between 2012 and 2025, VIIRS detected fire in 109,080 km² of Yunnan at least once. In an average year it detected fire in 15,170 km², ranking 3rd of 31 regions of China.
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 2014, with 24,870 km² detected; the quietest was 2022, with 8,410 km². The 2021–2025 average is 34% 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.
February, March and April together hold 56% of the fire-days in the record. The single busiest day was 12 February 2023, with detections in 1,000 cells.
Ground that burns again
Of the 109,080 km² with at least one detection, 22% had detections in three or more different years.
| Years with a detection | km² | Share |
|---|---|---|
| 1 year | 62,190 | 57% |
| 2 years | 23,040 | 21% |
| 3 to 5 years | 19,150 | 18% |
| 6 to 10 years | 4,360 | 4.0% |
| 11 years or more | 336 | 0.3% |
The half-degree square with the most fire-days is centred at 23.75, 103.25 and holds 4.8% of the region's fire-days.

- 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.
