This image, which utilizes information from the Copernicus Sentinel -3 objective’s radiometer instrument, reveals the temperature level of the land surface area in southern France, Spain, and northern Africa on the early morning of July 17,2022 It deserves keeping in mind the distinction in between air temperature level and land-surface temperature level. Air temperature level, given up our everyday weather report, is a procedure of how hot the air is above the ground. Land- surface area temperature level rather is a procedure of how hot the real surface area would feel to the touch. The image plainly reveals that, in some locations, the surface area of the land reached a massive 55 ° C (131 ° F). Considering Copernicus Sentinel -3 got these information in the early morning, the temperature level would have increased through the afternoon.

The series of heatwaves we are presently experiencing in western Europe is a clear indication of human-induced worldwide warming. ESA’s Clement Albergel discusses how we keep track of these occasions utilizing satellites such as the Copernicus Sentinel -3 objective and puts them in the context of the long-lasting environment information record created by means of ESA’s Climate Change Initiative.
Video Transcript:
The series of heatwaves we have actually been experiencing in Western Europe are the clearest indication of worldwide warming triggered by human activities, our emission of greenhouse gas in the environment.
To much better comprehend the irregularity of our environment system, we require observations. Satellite earth observations such as those run by the European Space Agency in cooperation with the European Commission in the context of the Copernicus Program are especially helpful as they offer worldwide protection, harmony, quick measurement, and connection.
Copernicus is powered by a devoted household of satellites, the Sentinels.
Sentinel 3 is an instrument a radiometer that determines land surface area temperature level. In the last 2 weeks of July, it has actually determined record-breaking land surface area temperature level. More than 45 degrees celsius in the UK, more than 50 degrees celsius in France, and more than 60 in Spain.
We can likewise integrate land surface area temperature level from Sentinel 3 with those from previous satellites in order to establish long period of time series. And that’s what we perform in the context of ESA’s environment program, the environment modification effort.
We assembled information from various satellites in order to establish worldwide scale long-lasting satellite-derived time series of essential parts of the environment system, likewise called important environment variables. Land surface area temperature level is among them.
We have actually just recently launched a 25 years environment information record of land surface area temperature level and the information suggest a steady boost of about 0.2 degrees celsius per years usually at an international scale with strong local irregularity.
Heat waves can likewise be followed by wildfire. Extremely heats integrated with low air humidity and dry plants increase the threat of wildfire in case there provides ignition.
Satellites are extremely helpful as they allow the tracking of various fire qualities. From a danger evaluation perspective, we can find locations that are dry and susceptible to wildfire break outs, we can keep track of actively flaming fires, smoldering fire, in addition to burn location, the scar let on the ground by fire. We can keep track of smoke plumes in addition to trace gas in the environment.
Another effect of extended heat waves when integrated to exceptionally low level of rainfall is dry spells. Soils are getting drier and numerous rivers in Europe have actually now reached level low record.
Images gotten by Sentinel -2 reveal part of the Po Valley near Piacenza in Italy and exposed how the river has actually diminished in between June 2020 and June2022 This is partly due to the absence of rainfall Northern Italy normally gets with exceptionally heats and the absence of snow in the mountain that normally feeds the river.
