Fire near Die

44.72°N, 5.34°E · first detected on 3 July at 02:39

What the satellites measured

This fire was tracked from 3 July at 02:39 to 11 July at 14:55, that is 9 days, through 1,234 satellite detections. The detected extent reaches 6,847 ha.

Detected extent: 6,847 ha
Cumulative power: 16,659 MW
Peak power, one pixel: 853 MW
VIIRS and MODIS detections: 1,234

These four figures cover the polar orbits alone, the ones that measure an area. The pass table below also counts geostationary detections, more frequent but too coarse for geometry, and its power column sums a whole pass where the peak above is that of a single pixel.

“Detected extent” is not “burned area”: it is the union of the ground footprints of the satellite pixels, and a pixel counts in full (375 m for VIIRS, 1 km for MODIS) 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 detection and are not an official assessment: only the emergency services and the competent authorities are authoritative.

Replay how the fire spread

The map is framed on this fire's footprint and loads only its detections. The timeline below covers the period in which satellites saw it, from the first to the last detection, with twelve hours before and twenty-four after; the ticks on the bar mark the emergency services' announcements that fall within it. The cursor opens on the most powerful pass, and playback replays the whole fire in about thirty seconds. “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. “24 h” stacks twenty-four hours : a fire stays visible between two satellite passes, which come two to four times a day. Both are true, but they say different things.

The detected extent

Outline of the burned area near Die, 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.

Before · 20 June 2026After · 24 July 2026

Sentinel-2, 10 m resolution. The dates are those of the least cloudy passes available: “after” is not the day after the fire went out, it is the first clear sky that followed. Contains modified Copernicus Sentinel-2 data (2026).

The spread, pass after pass

Die seen by Sentinel-2 on 2 July — 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.

Die seen by Sentinel-2 on 4 July — 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 11 days; beyond that, clustering would merge two successive fires in the same place.
