46.81°N, 0.15°E · first detected on 21 July at 13:30

What the satellites measured

This fire was tracked from 21 July at 13:30 to 6 August at 15:10, that is 16 days, through 159 satellite detections. The detected extent reaches 750 ha.

“Detected extent” is not “burned area”: it is the union of the ground footprints of the satellite pixels, and a 375 m pixel counts in full even when only a forest edge is burning. Compared with press figures it is in practice one and a half to three times the area reported. Detections taken at the edge of the scan swath, too coarse to measure anything at all, are excluded. These figures come from thermal satellite detection and are not an official assessment: only the local fire and civil protection authorities are authoritative.

Replay how the fire spread

The map is centred on this fire and loads only its detections. The timeline below covers the whole fire, from the first satellite pass to the last. “1 h” shows what is burning within an hour of the chosen moment : the map then follows the power curve below and empties when it falls. “12 h” stacks twelve hours , as the home map does, where stacking avoids an empty screen between two satellite passes. Both are true, but they say different things.

Outline of the burned area near Chouppes, drawn over satellite imagery
The outline is the union of the ground footprints of every satellite detection of this fire, from the first pass to the last. The background is the EOX cloudless Sentinel-2 mosaic, 2024 vintage: it shows the landscape BEFORE these fires, not the burn scar.

One image per usable Sentinel-2 pass, on the same framing throughout so that the comparison means something. The satellite comes back every two to five days and clouds rule out some of the passes: the gaps in the series are days without an image, not days without fire.

How the radiative power evolved

One point per satellite pass: the sum of the fire radiative power measured over the fire. This is the curve that says whether the fire eased off or picked up again, which no cumulative figure shows. The window covers 30 days; beyond that, clustering would merge two successive fires in the same place.
