The Swiss National GAW/GCOS Symposium promoted the role of consistent observations for understanding the Earth system across the water, energy and carbon cycles.

The threefold aim of the event was to:

  • Showcase achievements of the national GAW and GCOS programmes and their associated communities
  • Promote the understanding of the water, carbon and energy cycles and assess related observational gaps
  • Spark ideas for innovative and collaborative approaches across the broader Swiss GAW and GCOS communities

The outcomes of the symposium will form part of the future national GAW and GCOS programmes. Through the Swiss GAW and GCOS Offices, MeteoSwiss has published a white paper that outlines the most important outcomes of the symposium.

The white paper is now available here:

Target Audience

The Swiss National GAW/GCOS Symposium welcomed scientists and experts from the Swiss GAW and GCOS communities, the wider Swiss climate and earth science communities, as well as representatives who are active in the field of climate services or simply interested in observations and understanding of the earth system across the water, energy and carbon cycles.

Format of the Symposium

The Swiss National GAW/GCOS Symposium was held in a virtual format. There was a live broadcast of all presentations and discussions and the audience participated through an interactive online meeting platform.

Support

The Symposium was supported by the Swiss Academy of Sciences (SCNAT) through the Swiss Commission for Atmospheric Chemistry and Physics (ACP).
