Smoke from wildland fires, which have been burning within the Canadian province of Quebec for weeks, has crossed the Atlantic Ocean and darkened skies in southwestern Europe.
The Reasonable Decision Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite tv for pc acquired this picture within the morning (11:10 Common Time) on June 26, 2023. On the time, smoke drifted over northern Portugal and Spain. It additionally reached northward over different European international locations past the scope of this picture.
The smoke’s widespread attain is obvious within the map above. It reveals a plume of black carbon particles — generally referred to as soot — spanning eastward from North America and throughout greater than 2,000 miles of the Atlantic Ocean. The black carbon density information come from NASA’s GEOS ahead processing (GEOS-FP) mannequin, which assimilates information from satellite tv for pc, plane, and ground-based observing methods. Along with making use of satellite tv for pc observations of aerosols and fires, GEOS-FP incorporates meteorological information like air temperature, moisture, and winds to challenge the plume’s conduct.
Hazy skies in Europe have been additionally noticed by a world community of floor sensors referred to as the Aerosols Robotic Community, or AERONET. The community accommodates greater than 500 Solar photometer devices that measure aerosol optical depth (AOD) world wide. On the morning of June 26, AERONET sensors in northern Spain and France measured AODs larger than 0.5. The AOD in these areas is often near 0.1. (For reference, a superbly clear sky would have an AOD of lower than 0.05, whereas an AOD of three would make it troublesome to see the Solar.)
But air high quality within the smoke-covered components of Europe on June 26 remained largely honest, in comparison with unhealthy and dangerous air high quality within the smoke-affected components of Canada and the US. That’s as a result of many of the smoke that reached Europe was increased within the ambiance, the place it’s much less more likely to have an effect on human well being.
Smoke from wildfires in Canada has drifted proper throughout the Atlantic Ocean and is now evident on satellite tv for pc imagery throughout western Europe

Nonetheless, the smoke over Europe will possible be observed by individuals. Based on the UK Met Workplace, the smoke aerosols might contribute to vivid sunrises and sunsets.

I do not like paywalls. You do not like paywalls. Who likes paywalls? Right here at CleanTechnica, we carried out a restricted paywall for some time, nevertheless it all the time felt improper — and it was all the time robust to resolve what we must always put behind there. In concept, your most unique and finest content material goes behind a paywall. However then fewer individuals learn it! We simply don’t love paywalls, and so we have determined to ditch ours.
Sadly, the media enterprise remains to be a troublesome, cut-throat enterprise with tiny margins. It is a endless Olympic problem to remain above water and even maybe — gasp — develop. So …
