Aerosol-Cloud Coupling and Climate Interaction in the Arctic (ACCACIA) is a project to study the processes that control the properties of low-level clouds (stratus and stratocumulus) in the Arctic – the sources of aerosol particles, their interactions with cloud microphysical properties, the radiative properties of the clouds, and the dynamic coupling with the lower atmosphere.
ACCACIA will undertake two measurement campaigns in the spring and summer of 2013, timed to coincide with the periods of minimum and maximum extent of Arctic sea ice. Measurements will be made from a research ship in and around the marginal ice zone close to Svalbard, and from two research aircraft: the FAAM BAe146, and the BAS MASIN Twin Otter.
The ACCACIA project is undertaken by a consortium of research groups:
- University of Leeds – School of Earth and Environment
- University of Manchester – School of Earth, Atmospheric, and Environmental Sciences
- University of York – Department of Chemistry
- University of East Anglia – School of Environmental Sciences
- British Antarctic Survey
