Unraveling the connection between Canadian wildfires and Arctic ice clouds
Ice nucleating particles as a kind of aerosols have a significant impact on the Arctic climate by promoting the formation of ice clouds at a temperature above -- 38 degrees Celsius. Wildfires in mid-latitudinal areas are a major source of these aerosols. However, a direct observation of wildfire-emitted aerosols facilitating ice cloud formation has never been documented. Now, using field and climate data, scientists have linked aerosols emitted by Canadian wildfires in 2023 to the formation of ice clouds over the Arctic Ocean.
