About This Position

Isotope ratio measurements are a key part of our efforts to understand sources and sinks of the major greenhouse gases CO2, CH4 and N2O. Harmonised and standardised field calibration and measurement methods are required to support isotopic measurements in networks such as the Integrated Carbon Observation System (ICOS). The METHIR project is a major European effort aimed at improving field isotope ratio measurements harmonisation and calibration, with direct linkages to current measurement networks.

Key Responsibilities

• Continue development of a flask sampling system for isotopic measurements of N2O from background sites, including testing at the Jungfraujoch.
• Measurement of N2O isotopic composition in flask samples from Jungfraujoch and other sites using the RAPTOR-QCLAS system.
• Collaboration with Swiss and international research groups to improve the N2O isotopic record from preindustrial to present day t...
