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
