Between 2012 and 2025, VIIRS detected fire in 134 km² of Västernorrland at least once. In an average year it detected fire in 9.7 km², ranking 11th of 21 regions of Sweden.
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 2018, with 28 km² detected; the quietest was 2017, with 3.9 km². The 2021–2025 average is 32% 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.
June, July and August together hold 63% of the fire-days in the record. The single busiest day was 19 July 2018, with detections in 15 cells.
Ground that burns again

- 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.
