The Horizon Europe project isoMET connects twelve research institutions to improve

1. ambient air monitoring capabilities for CH4 isotopes;
2. the quality of source signature information;
3. the modelling information necessary to direct the measurement strategy and make top-down emissions estimates. 

The contribution of Empa focuses on the development and application of high-precision mid-IR laser spectroscopy for the analysis of the rare doubly substituted isotopic species 13CH3D/12CH2D2 in methane to perform cutting-edge studies of process-derived and ambient methane.
