Post-doctoral position, Atmospheric Oxidation Monitoring, Cranfield University, UK (Deadline: 07.05.2025)

The successful applicant will work principally on a new project which involves the integration of the gas chromatograph with photo-ionisation detector (iDirac) with an Atmospheric Oxidation Module in order to produce an OH reactivity instrument capable of measuring autonomously in the background atmosphere. After testing in the University of Leeds’ Highly Instrumented Reactor for Atmospheric Chemistry, four further versions of the iDirac-AOM will be constructed and deployed at clean air monitoring observatories to measure the OH reactivity in the background atmosphere. These measurements will inform the understanding of OH concentrations and give more confidence in estimates of the removal rate and lifetime of methane. Continued measurements over time would allow any changes in OH reactivity to be observed.
