Analyses of organic matter aerosol optical depth, based on 🛰️ obs, showing large-scale smoke transport around N Hemisphere from #Siberia #ArcticFires (& #CaliforniaFires) between 1 Aug to 2 Sept 2020. @CopernicusECMWF Atmosphere Monitoring Service @ECMWF atmosphere.copernicus.eu
#ArcticFires were very active in first week of August 2020 but reduced to more usual activity for most of the month with slight increase as summer came to an end. #opendata from #CopernicusAtmosphere Global Fire Assimilation System based on MODIS 🛰️ obs confluence.ecmwf.int/display/CKB/CA… 
Peak #ArcticFires activity seems a long time ago but Sakha Republic & Chukotka🇷🇺still experiencing above average daily total #wildfire intensity for late August in #CopernicusAtmosphere GFAS data to 24/08. #TerraMODIS🛰️imagery shows continuation on 25/08 go.nasa.gov/3ldIDKV
#Wildfire activity in other parts of #Siberia has been relatively low all summer. Krasnoyarsk & Irkustk have been experiencing increased daily total intensity over last 2 weeks close to 2003-2018 mean & << 2019.

Greatly reduced #ArcticFires over the last week in #CopernicusAtmosphere GFAS data as the season starts to change although latest map atmosphere.copernicus.eu/charts/cams/fi… shows several continuing active #wildfires in #Siberia south of the #ArcticCircle
Have we seen the end of this year's #ArcticFires? Cloud still limits🛰️obs but #ArcticCircle #wildfires expected to die down in 2nd half August based on 18 years of #CopernicusAtmosphere Monitoring Service GFAS data. 240 Mt CO2 since 1 June 2020 higher than previous annual totals.

Cloud affecting NASA #AquaMODIS🛰️obs go.nasa.gov/3h6C7mA & daily intensity of #ArcticCircle #wildfires possibly leading to last few days of 2020 #ArcticFires if following 2019 & 2003-2018 average in #CopernicusAtmosphere Monitoring Service GFAS data confluence.ecmwf.int/display/CKB/CA…
Comparing #wildfires in different regions of #Siberia & far eastern #Russia since between 1 June to 11 August shows #ArcticFires differences between 2020 & 2019: most activity in Sakha Republic (&Chukotka) but much less activity in Krasnoyarsk & Irkutsk.

Early August #ArcticFires continuing at similar daily total intensity to 2019 in #CopernicusAtmosphere Monitoring Service GFAS data confluence.ecmwf.int/display/CKB/CA…. Latest CO forecast atmosphere.copernicus.eu/charts/cams/ca… shows high values over #Siberia & residual smoke over NE Canada & N Atlantic
High values of total column CO over Hudson Bay but mid-troposphere (~5km altitude) concentrations show smoke from #ArcticFires already across N Atlantic & N+W Europe in latest #CopernicusAtmosphere Monitoring Service 12-hour forecast. More charts➡️atmosphere.copernicus.eu/charts/cams/ca…
New precedent in scale & intensity of #Siberia/#Arctic #wildfires compared to previous 17 years in the #Copernicus Atmosphere Monitoring Service GFAS data based on MODIS obs confluence.ecmwf.int/display/CKB/CA… (145 Mt CO2 in July 2020 vs. 182 Mt CO2 total for 2019) #ArcticFires
Daily cumulative estimated #ArcticCircle #wildfire carbon emissions for 2020 (red) were already increasing faster than in 2019 (gold) but increased significantly in the 2nd half of July
Comparing the annual total estimated #wildfire CO2 emissions for the #ArcticCircle from 2003 to 2020 (up to 31 July 2020) shows that this year is already the highest for the region in the GFAS dataset.

Interesting to note low pressure system to north of Chukchi & East Siberian Seas leading to recirculation of smoke back to Siberia via N Pole. Leading edge could reach northern Greenland towards the weekend.
July 2020 has witnessed escalation in #ArcticFires previously unseen in #CopernicusAtmosphere Monitoring Service GFAS data. #ArcticCircle daily total FRP >> 2019 & July total estimated #wildfire carbon emissions almost double 2019 (2019 annual total was 50 megatonnes carbon).
First, (very) rough, look at estimated surface deposition of black carbon over the #Arctic Ocean from 21-24 July with #CopernicusAtmosphere Monitoring Service model output. Clear increase (> 0.1 mg/m2) across Chukchi Sea region originating from #Siberian #ArcticFires

Friday deep dive into #ArcticFires of Siberia, focusing on the 8,000+ fires detected by MODIS & VIIRS satellites between May 2020 and mid-July 2020 at latitudes above 70°N. (A thread).
Important to note that Arctic fire regimes are not novel, but seem to be increasing in number. Here, @iccinet Climate Change Intern and @StOlaf undergraduate student, @BradenPohl, maps fires for last 3 years in northern Krasnoyarsk Krai and Sakha Republic.

Another big increase in #ArcticCircle daily total #wildfire radiative power on 21 July, well above 2019 max daily total, with July total estimated carbon emissions almost catching up to 2019. #CopernicusAtmosphere Monitoring Service GFAS data confluence.ecmwf.int/display/CKB/CA… #ArcticFires
#AquaMODIS visible imagery for 22 July shows the spatial extent of the fire activity is continuing, producing vast amounts of smoke, & another possible increase in the fire monitoring tomorrow.
New spatial analysis of wildfires across the Arctic in May/June 2020, and how they compare to the satellite record (2003-2020). What is burning? Are there peat fires? What about permafrost? 🔥🛰️thread in collab with @m_parrington @CopernicusECMWF #ArcticFires [1/9]
The Arctic Circle is an ecologically arbitrary line, so I also investigated fires burning north of the treeline, using @NSIDC's tundra & boreal forest boundary, a better representation of the Arctic Zone. May/June 2020 saw 10x more fires than 2003-18 average for this zone. [2/9]
Using a Global Landcover dataset, we see corroborating evidence that the spike in fire activity in 2019/20 occurred in both the boreal forest (tree cover) and tundra (herbaceous & shrub cover) ecosystems of the Arctic Circle [3/9]
