Beschrijving
English: During 2019, Siberia faced the worst fire crisis the country has seen in many years. On 31 July 2019, Russian authorities reported that 3 million hectares were on fire, an area roughly the size of Belgium. Wildfires continued until the end of summer, when snow covered all the burn scars. What we see here is a comparison of two images captured by one of the Copernicus Sentinel-2 satellites acquired almost a year apart. The first taken on 8 June 2019 and the second on 7 June 2020 after the arctic region of Siberia, along the Lena River was ravaged , by severe wildfire during July and August 2019. Only after 10 months, it is possible to evaluate the real size of burnscar using Earth observation data, allowing us to measure the largest site and maximum length reach of 83 km. The two images have been rendered with a false colour combination of the Copernicus Sentinel-2 bands, including the Short-Wave InfraRed channels that are widely used in vegetation monitoring, as well as in several wildfire monitoring applications.
