Only fires of 2,000 ha or more get an entry: smaller ones are not in the lists or the entry totals, but they are in the GWIS yearly series.

Fires of 2022, largest first · 37

Burned area in 2022 (Copernicus Land, Sentinel-3)

According to Copernicus Land, 2,593,372 ha burned in 2022: rank 7 of 7 complete years (1 = the most burned). The average of those years is 3,653,436 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.
