Assessing National Halocarbon Emissions Using Regional Atmospheric Measurements

To mitigate the environmental impacts of synthetic halocarbons it is crucial to quantify their emissions to the atmosphere on different spatial scales. For this, top-down modelling approaches were developed, relying on atmospheric concentration observations. However, increased sensitivity on country-scale is needed, requiring a denser measurement network and models operating on a regional scale. In this light, we conducted an extensive study to assess Swiss halocarbon emissions, with high sensitivity to the regional emissions sources.
