Following an active 2019 season, fires in 2020 have again been abundant, widespread, and have produced abnormally large carbon emissions.
Abnormally warm temperatures have spawned an intense fire season in eastern Siberia this summer. Satellite data show that fires have been more abundant, more widespread, and produced more carbon emissions than recent seasons.
The area shown in the time-lapse sequence above includes the Sakha Republic, one of the most active fire regions in Siberia this summer. The images show smoke plumes billowing from July 30 to August 6, 2020, as observed by the Visible Infrared Imaging Radiometer Suite (VIIRS) on NASA/NOAA’s Suomi NPP satellite and the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite. Strong winds occasionally carried the plumes as far as Alaska in late July. As of August 6, approximately 19 fires were burning in the province.
“After the Arctic fires in 2019, the activity in 2020 was not so surprising through June,” said Mark Parrington, a senior scientist at the Copernicus Atmosphere Monitoring Service (CAMS) of the European Centre for Medium-Range Weather Forecasts. “What has been surprising is the rapid increase in the scale and intensity of the fires through July, largely driven by a large cluster of active fires in the northern Sakha Republic.”
