How do clouds form in Antarctica? The first flight-based aerosol measurements in 20 years‎

Antarctica plays a crucial role in Earth's climate system by reflecting solar radiation back into space. The large white ice surfaces and clouds play a decisive role in this process. However, how clouds actually form in Antarctica, how they interact with the atmosphere and what role aerosols play in this process has not been sufficiently researched to date. Engaging in the SANAT flight campaign, the Alfred Wegener Institute, the Leibniz Institute for Tropospheric Research and the Max Planck Institute for Chemistry aim to help close this knowledge gap. The flight-based aerosol measurements conducted in Antarctica are the first of their kind in 20 years and also the first to extend deep into the interior.
