Any kind of scientific research on atmospheric chemistry and physics related to mountain sites is welcome. This includes all gaseous compounds such as greenhouse gases, short-lived reactive gases, intermediate and long-lived species, as well as physical and chemical properties of aerosols, physical and chemical characterization of clouds and precipitation, vertical and horizontal transport, and any dynamic and meteorological processes related mountain sites. An important aspect will be the further integration of observations and modelling activities. To enable intensive discussions among the various communities, all presentations will be given as plenaries, without split into special sessions.
