[Met-jobs] PhD studentship: Balancing the global methane budget

From Matthew Rigby <>
Date Tue, 20 Nov 2012 13:34:25 +0000

PhD studentship at the University of Bristol, UK

Supervisors: Matt Rigby (School of Chemistry) and Ed Hornibrook (School of 
Earth Sciences)

Methane is produced and released from a range of natural and human sources, and 
is second only to carbon dioxide in its contribution to man-made ‘global 
warming’. However, a great deal of uncertainty remains about the drivers of 
current atmospheric methane variability. Measurements of the isotopologues of 
methane have the potential to provide a wealth of useful information for 
understanding the methane cycle, because different sources emit methane with 
different isotopic compositions. This project will re-evaluate stable isotope 
signatures currently assigned to methane emission sources and sinks and, where 
necessary, will involve new measurements for recently identified and 
significant sources of methane. The re-assessed values will then be used in a 
new ‘inverse model’ framework for the global methane cycle. Sources will be 
re-evaluated using measurements of the concentration and stable isotope 
composition of atmospheric methane obtained from a global network of monitoring
