The Swiss National GAW/GCOS Symposium 2026 is a premier scientific event bringing together climate researchers, atmospheric scientists, policy makers, and environmental experts to discuss developments in global atmospheric observation, climate monitoring, and sustainability research. The symposium highlights the work of the Global Atmosphere Watch (GAW) and the Global Climate Observing System (GCOS) in improving climate data quality and environmental monitoring.

The programme includes keynote presentations, technical sessions, and interactive discussions, covering topics such as atmospheric composition, greenhouse gas monitoring, climate indicators, data analysis methodologies, and policy implications. Participants explore ways to strengthen observation networks, enhance data accessibility, and support climate-informed decision-making.

By fostering knowledge exchange, collaboration, and innovation, the Swiss National GAW/GCOS Symposium 2026 advances climate research, environmental stewardship, and sustainable policy development in Switzerland and globally.
