Closing the global budget of one of the atmosphere’s most potent greenhouse gases
Matt Rigby (Bristol), Simon O’Doherty (Bristol), Mike Czerniack (Edwards Ltd.), Alistair Manning and Tim Arnold (UK Met Office)We are seeking applicants for a fully funded PhD studentship working with Edwards Ltd. (Clevedon, UK). Measurements from the Advanced Global Atmospheric Gases Experiment (AGAGE, agage.mit.edu) show that only around 50% of global tetrafluoromethane (CF4) emissions can be explained by current emissions inventories. This “missing source” is of concern because CF4 is a particularly strong infrared absorber (i.e. greenhouse gas) with a very long lifetime (around 50,000 years). Despite efforts by the semiconductor and aluminium industry to reduce emissions of this gas, AGAGE observations show that it continues to grow rapidly in the atmosphere. We propose to examine the global atmospheric CF4 budget using a new approach involving updated estimates of potential sources, global and regional atmospheric chemical transport models and AGAGE observations. Using this method, we will derive a comprehensive estimate of global CF4 emissions. It is hoped that this work, which brings together academia, industry and regulators, will contribute significantly to future efforts to reduce CF4 emissions.
