Since the last Quadrennial Ozone Symposium that took place in Edinburgh in 2016, a variety of new developments have taken place on all facets of atmospheric ozone, including its observation and impact on human health and ecosystems. The Symposium’s program will address all these aspects. Key topics will include: stratospheric and tropospheric ozone observations and modelling; interactions between ozone, atmospheric chemistry and climate; ozone-depleting substances, sources, sinks, and budgets; ozone measurement techniques; and effects on human health, ecosystems, and agriculture. Engagement with stakeholders and policymakers is also a key feature.

Global Atmosphere Watch Programme (GAW) of the World Meteorological Organization (WMO) will provide financial support to selected young scientists participating in the Quadrennial Ozone Symposium upon recommendation from the International Ozone Commission (IO3C). Interested individuals should submit short CV and a copy of their Abstract for review to secretariat@qos2021.org not latter than 31 May 2021.

Early Career Scientist (ECS) is defined as a student, a PhD candidate, or a practicing scientist who received their highest certificate (e.g. BSc, MSc or PhD) within the past seven years which is younger than 35 years. The seven-year period can be extended to allow for periods when the scientist was not working in science because of, but not limited to, caring and/or parental responsibilities, disability, personal illness, community obligations or national service. For defining eligible individuals, we propose not using the country of origin but studying or practicing in country classified as having Low and middle income by the World Bank.
