GAWTEC & YESS Webinar Series Reactive Gases: Christoph Zellweger - Measurements tropospheric ozone
Surface ozone is both a greenhouse gas and a secondary air pollutant which is harmful to human health and ecosystem productivity. It is not directly emitted but formed by chemical reactions of so-called ozone precursors (mainly nitrogen oxides, carbon monoxide, methane and non-methane volatile organic compounds) in the presence of sunlight. Since surface ozone is a regulated air pollutant, accurate and reproducible measurements are required.
This webinar gives an overview of ozone measurements in the Global Atmosphere Watch (GAW) programme and covers the following topics
- History of ozone measurement techniques
- Current measurement techniques for surface ozone
- Measurement setup
- Station settings and requirements
- Traceability, calibration and quality assurance of surface ozone measurements
- Overview of standards and guidance documents
