It’s been a particularly brutal wildfire season in parts of western North America, as several large blazes continue to cause headaches from California up to British Columbia.
As shocking new satellite images show, the smoke from these fires hasn’t been limited to the west coast, or even the North American continent.
It’s drifted all the way over the Atlantic Ocean into European skies.
This series of images was produced by the Ozone Mapping Profiler Suite (OMPS) on Suomi NPP satellite, and they show aerosol concentrations from September 4 to 7.
Aerosols are a mixture of fine solid particles or liquid droplets, with smoke being a good example of the former.
High aerosol concentrations are shown in dark orange-brown, while lower concentrations are shown in yellow.
