English: Wildfires are ravaging several areas of Siberia, including those inside the Arctic Circle. While fires are common at this time of year, record temperatures and strong winds are making the situation particularly worrying. Satellite data are extremely useful to detect fires and to monitor hotspots. In 2019, one of the Copernicus Sentinel-2 satellites detected what is believed to be the northernmost wildfire in recent years, 30 km west of Taymylyr in the Republic of Sakha. This year, a Copernicus Sentinel-2 satellite imaged a fire further north (Latitude 72.723° N, Longitude 118.12° E), 12 km north of the 2019 fire and only 50 km from the Arctic Ocean. The European Union’s Copernicus Sentinel-2 and Sentinel-3 satellites use infrared sensing capabilities to detect active fires, subject to cloud cover. Moreover, data derived from the Copernicus Sentinel-3 satellites’ measurements can provide estimates of the fire radiative power (FRP). This parameter is related to the amount of organic material a given fire is burning and to the amount of smoke it is releasing. The combined use of data derived from these Copernicus satellites can provide important improvements in terms of monitoring and understanding the impact of climate change.
