Fires of 2023, largest first · 44

Burned area in 2023 (Copernicus Land, Sentinel-3)

According to Copernicus Land, 17,829,947 ha burned in 2023: rank 7 of 7 complete years (1 = the most burned). The average of those years is 20,457,840 ha.

The area the Sentinel-3 satellite sees burned each month, separate from the fire pages. It is the same source and the same method every year, so years can be compared with each other. It counts everything that burns, including crop and pasture burning, which is why it does not match the fire pages or the official statistics.

Fire-page areas are satellite-measured perimeters and may differ from official statistics. The yearly and weekly record is the Copernicus GWIS estimate. The FWI is our own calculation from ERA5 at each fire's location: it is not an official danger warning.
