CAESAR: Cold Air Outbreak Experiment in the Sub-Arctic Region

Summary

The PI team proposes a dedicated field campaign, Cold Air Outbreak Experiment in the Sub-Arctic Region (CAESAR), to examine the structure of marine boundary layer clouds during CAOs. CAESAR will deploy the NSF/NCAR C-130 aircraft, with in situ and remote sensors sampling Arctic air masses from the CAO origin at the ice edge throughout their transformation downstream. A rich array of airborne radars and lidars, aerosol, cloud, precipitation, and trace gas probes, deployed during CAO events over the open waters between northern Sweden and the Arctic ice edge for 45 days in early 2024, will provide a detailed characterization that will form the backbone of modeling studies across a range of scales and form a long-lasting legacy dataset.
