Antarctic Clouds and Aerosols (ACA, www.scar.org/science/aca/about/) is one of the Action Groups of the Scientific Committee on Antarctic Research (SCAR) and holds its regular meetings following the EGU session Clouds and Precipitation in the Polar Regions. Observationalists and modelers working on the Arctic and Antarctic aerosols/moisture/clouds/precipitation/blowing snow and other related processes are welcome to participate. Agenda for this year meeting includes a metadata base on Antarctic cloud/precipitation measurements being setup by the British Antarctic Survey, a network of low-cost instrumentation (ceilo, MRR...), and some ongoing and planned field campaigns. Other topics are welcome.
