1st Swiss National GAW/GCOS Symposium 2021: White Paper

The Global Atmosphere Watch (GAW) and Global Climate Observing System (GCOS) are international activities to coordinate long-term systematic observations of the composition of the atmosphere and the climate system as well as regularly assess the status of global climate observations and produce guidance for their improvement. They also facilitate services in the areas of climate, air quality and health. Switzerland implements GAW and GCOS programmes through GAW-CH and GCOS Switzerland. Both national programmes are coordinated by MeteoSwiss and implemented in partnership with a network of research and environmental institutions.
