Welcome Message from the CAS President

The mission of CAS is to support research in atmospheric sciences with the aim to prepare societies when natural disasters strike, to protect the environment and to ensure that the responses to environmental change are well informed. Meteorological services are more and more science driven. Together, research, the strategy for communication of weather and climate information and the underlying data policy are essential for the development of services with a high return on the investments in meteorology. In short, the mission of CAS is "science for service".

The integration of the earth system components is another essential challenge in atmospheric sciences. Accurate determination of the fluxes of sensible and latent heat, momentum, biogeochemical trace species and water is essential in weather prediction, climate projections and reanalysis, in hydrology and in environmental analysis and predictions. The atmosphere is coupled with the land surface, oceans, ice and with ecosystem processes.

The role of CAS is to facilitate global atmospheric research by fostering good planning processes of essential projects. It is further to encourage and motivate WMO Member countries to direct their national resources towards these projects, to provide the mechanisms for good governance of these global efforts, and support the efforts to improve meteorological services as mature results arise from the research work.
