Monitoring and Modelling of F-Gases and Ozone Depleting Substances

Session ID#: 159577

Session Description:
The reduction of the atmospheric burden of ozone depleting substances and their replacement gases, controlled under the Montreal Protocol, has led to the onset of stratospheric ozone recovery and has translated into the largest single policy effort to curb global warming to date. F-gases, such as HFCs, PFCs, SF6 and NF3, are reported under the UNFCCC, and have shown significant growth over the past few decades. To ensure future ozone recovery, monitor compliance with the Protocol, and mitigate climate impacts it is important to understand the full lifecycle of these gases – from production and consumption to emissions, transport, role in the composition of the atmosphere and eventual destruction.  

This session provides a broad forum for discussion of ozone depleting substances and F-gases. We welcome papers on monitoring and modelling of these gases, their role in a warming climate and policy-relevant aspects. We also welcome studies that use remote sensing and in situ observations of these gases to understand atmospheric transport processes, chemistry and composition.
