Shocking satellite images have revealed the extent of the damage caused by wildfires as the heatwave swept across western Europe this week.
The images were taken by the European Space Agency’s Copernicus Sentinel-3 – a satellite that orbits 506 miles (814.5km) above Earth’s surface to measure our planet’s oceans, land, ice, and atmosphere.
Photos taken in the southern Gironde region in France on 12 July and 17 July show smoke and patches of scorched earth, highlighting the extent of the damage caused by wildfires because of the heatwave.
ESA also released a heat map showing the land surface temperatures in southern France, Spain and northern Africa on the morning of 17 July.
‘In some places the surface of the land reached a whopping 55°C [131°F],’ the European Space Agency explains.
‘Considering Copernicus Sentinel-3 acquired these data in the morning, the temperature would have increased through the afternoon.’
In other side-by-side images taken on 12 July and 17 July, the burn scar and active hotspots can be seen near La Teste-de Buch, where wildfires reached all the way to the beach

Air temperature is the measurement used for our daily weather forecast, and is a measure of how hot the air is above the ground.
However, land-surface temperature is a measure of how hot the actual surface of the ground would feel to the touch.
‘Scientists monitor land-surface temperature because the warmth rising from Earth’s surface influences weather and climate patterns,’ ESA explained.
‘These measurements are also particularly important for farmers evaluating how much water their crops need and for urban planners looking to improve heat mitigating strategies, for example.’

In one set of satellite images taken on 12 July and 17 July, the scars left by wildfires around the commune of Guillos and near the town of Cazaux in southwestern France can be seen.
‘On 12 July 2022, two major wildfires broke out in southwestern France,’ ESA explained.
‘The wildfires have heavily affected local communities: more than 16,000 people have been evacuated in total, and road closures have been put in place.
‘Despite the magnitude of the fires, there has not been any reported casualties.’

The Copernicus Sentinel-2 satellite carries an innovative wide swath high-resolution multispectral imager with 13 spectral bands.
This provides a new perspective of our land and vegetation, according to ESA, with its shortwave infrared channel used to highlight heat from the wildfire.
In other side-by-side images taken on 12 July and 17 July, the burn scar and active hotspots can be seen near La Teste-de Buch in southwestern France, where wildfires reached all the way to the beach.
‘The Copernicus Emergency Management Service has been activated to respond to many of the fires that are plaguing Europe at the moment, including those impacting Gironde,’ ESA explained.
‘The service takes advantage of observations from several satellites to provide on-demand mapping to help civil protection authorities and the international humanitarian community in the face of major emergencies.’

As well as France, Spain and the UK have also experienced severe wildfires amid the heatwave.
On 17 July, a blaze ignited near Losacio in the Province of Zamora in the Spanish autonomous region of Castilla y Léon.

Heat warnings are still in force across many parts of Europe, while drought warnings are also in place across half of the European Union bloc.
‘As the effects of climate change increase, the fear is that these kind of weather extremes will increase also,’ ESA concluded.
‘Satellites orbiting the planet play an important role in delivering data to understand and monitor how our world is changing – data that are key for mitigation strategies and policymaking.’
