Following unusually dry conditions and high temperatures, several wildfires have occurred in Canada since the beginning of May.

They started in the western part of the country but later spread to the eastern regions, leading to a total of approximately 160 megatonnes of carbon emissions, which is now the largest total annual estimated emission for Canada based on the global fire assimilation system “CAMS”.

A further increase in the intensity of wildfires in Quebec and Ontario late last week (June 21-22) led to a global CAMS forecast showing a particularly strong episode of long smoke transport crossing the North Atlantic and reaching Europe, with high aerosols and optical values ​​of carbon monoxide, between June 26 and 29.

It’s important to note that long-range smoke transport, such as this episode, tends to occur at higher altitudes where air pollutants have a longer lifetime in the atmosphere, meaning they manifest more as hazy skies. with a red/orange sunset.
