Collaborative Research: A multi-faceted evaluation of aerosol impacts on Arctic clouds
The project will utilize results from several Arctic measurement sites, including long-term observations at Barrow, Alaska, and shorter-term observations from Summit, Greenland, and two measurement campaigns over the Arctic Ocean to improve upon previous estimates of Arctic aerosol-cloud interaction...

The project will utilize results from several Arctic measurement sites, including long-term observations at Barrow, Alaska, and shorter-term observations from Summit, Greenland, and two measurement campaigns over the Arctic Ocean to improve upon previous estimates of Arctic aerosol-cloud interactions. To do this a critical first step will involve understanding the conditions under which surface aerosol conditions, as generally used in the compilation of statistical datasets addressing this issue, are comparable to those at cloud level. Using a variety of techniques, the distinction between surface-coupled and decoupled cloud states will focus evaluation of aerosol-cloud interactions on appropriate cases, reducing statistical contamination. From these cases, a statistical evaluation will be performed to reveal co-variation between key cloud (e.g. liquid water path, ice water path) and aerosol (e.g. concentration, size, hygroscopicity) properties. Combined with surface radiation measurements and idealized radiative transfer simulations, the results from this evaluation will provide an improved estimate of the net radiative impact of aerosols on Arctic clouds.
