In current weeks, devastating wildfires have unfold in Greece, Italy, Spain, Portugal, Algeria, Tunisia and Canada, inflicting human casualties in addition to large environmental and financial injury.
Whereas wildfires are a pure a part of many ecosystems, scientists have warned that they’re turning into more frequent and extra widespread. In response, an upgraded model of ESA’s World Fire Atlas is now accessible offering an in depth evaluation of wildfires throughout the globe.
Rising world temperatures and the elevated frequency of utmost climate occasions has led to a surge within the variety of wildfires quickly consuming intensive areas of vegetation and forested lands. International locations like Greece and Italy have already skilled the devastating impression of large-scale blazes.
The European Forest Hearth Data System (EFFIS) has reported that, as of 29 July 2023, greater than 234 516 hectares of land throughout the European Union has already been burned this yr alone. The state of affairs requires pressing consideration and efficient measures to fight the rising hazard posed by these wildfires.
In mild of the extreme wildfires, ESA has reopened its World Fire Atlas which provides an perception into the distribution of particular person fires going down at each a nationwide and world scale.
By way of its interactive dashboard, customers can examine the frequency of fires between nations in addition to analyse the evolution of fires going down over time. The atlas initially opened in 2019, the place it supported each European civil safety businesses and firefighters.
The dashboard makes use of night-time knowledge from the Sea and Land Floor Temperature Radiometer (SLSTR) on board the Copernicus Sentinel-3A satellite tv for pc. Working like a thermometer within the sky, the sensor measures thermal infrared radiation to take the temperature of Earth’s land surfaces which is used to detect the fires.
Even when the atlas can’t decide up all fires due to satellite tv for pc overpass constraints and cloud protection, it’s statistically consultant from one month to the opposite and from one yr to the opposite. Information from the Copernicus Sentinel-3B satellite tv for pc will probably be added in December 2023.
Over the earlier seven years, knowledge from the World Hearth Atlas present a considerable variety of fires detected in Portugal, Italy, Greece, France and Spain with the best variety of fires reached in Portugal in August 2016 and October 2017.
Information additionally present that Canada has skilled 11 598 fires throughout the first seven months of 2023. It is a 705% enhance in comparison with the typical quantity of fires detected over the identical interval (from 1 January to 31 July) of the earlier six years (from 2017 to 2022).
Canada is presently battling the nation’s worst wildfire season on report, with greater than 10 million hectares of land burned, which is claimed to extend within the coming weeks.
ESA’s Olivier Arino mentioned, “The relaunch of the World Hearth Atlas presents a beneficial alternative for authorities, researchers and organisations to boost their understanding of fireside occurrences worldwide. By utilising this complete useful resource, they’ll devise more practical methods for hearth prevention and administration on a world scale.
“The continuing dedication of ESA, Copernicus and the EU to repeatedly present this beneficial useful resource reinforces the significance of leveraging area know-how to deal with vital environmental challenges.”
