Antarctic research finds exceptional warm air intrusions and omnipresent aerosol layers in the stratosphere

Extremely clean air on the ground, warm air intrusions and sulfate aerosol at high altitudes—a Leipzig research project has gained new insights into clouds in Antarctica. From January to December 2023, the vertical distribution of aerosol particles and clouds in the atmosphere above the German Neumayer Station III of the Alfred Wegener Institute, Helmholtz Center for Polar and Marine Research (AWI) was investigated from the ground for the first time.
