Between 2012 and 2025, VIIRS detected fire in 27,470 km² of Arizona at least once. In an average year it detected fire in 2,500 km², ranking 18th of 51 regions of United States.
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 2020, with 4,630 km² detected; the quietest was 2013, with 1,340 km². The 2021–2025 average is 36% higher 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.
June, July and August together hold 48% of the fire-days in the record. The single busiest day was 17 June 2020, with detections in 366 cells.
Ground that burns again
Of the 27,470 km² with at least one detection, 4.3% had detections in three or more different years.
| Years with a detection | km² | Share |
|---|---|---|
| 1 year | 22,100 | 80% |
| 2 years | 4,180 | 15% |
| 3 to 5 years | 1,060 | 3.9% |
| 6 to 10 years | 96 | 0.4% |
| 11 years or more | 30 | 0.1% |
The half-degree square with the most fire-days is centred at 33.25, -110.75 and holds 13% 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.
