Emissions of greenhouse gases (GHGs) reported by countries in their GHG inventories to UNFCCC (United Nations Convention on Climate Change) represent the central information used in international policies to curb global GHG emissions in order to meet the targets of the Paris Agreement on climate change.
To verify the implementation of the several treaties
involving the reduction on use of HFCs - such as the Kigali Amendment to the Montreal Protocol (2016), the EU F-gas regulation (2014), and the EU-MAC directive (2006)- results based on reliable and continuous atmospheric observations are crucial.
Fluorinated halocarbons are potent GHGs (GWPs to ~24000) whose concentration are expected to continue growing in the future; but are challenging compounds due to their extreme high volatility and the very low atmospheric concentrations.
Here we present results based on atmospheric observations made at the WMO GAW (World Meteorological Organisation Global Atmosphere Watch) station of Monte Cimone ISAC-CNR (CMN) in the frame of the AGAGE (Advanced Global Atmospheric Gases Experiment) network based on MEDUSA system.
