A central arctic extreme aerosol event triggered by a warm air-mass intrusion
International audience Frequency and intensity of warm and moist air-mass intrusions into the Arctic have increased over the past decades and have been related to sea ice melt. During our year-long expedition in the remote central Arctic Ocean, a recordbreaking increase in temperature, moisture and...
