Tim Arnold

Senior Research Scientist

Before joining NPL and the University of Edinburgh, Tim was a Senior Scientist at the Met Office Hadley Centre. Prior to this, he spent more than five years in the USA at the University of California, San Diego, as a postdoctoral scholar studying atmospheric composition change. Tim holds an MSci in Natural Sciences from the University of Cambridge and a PhD in isotope geochemistry from Imperial College London.

Current interests

Tim's research helps improve our understanding of the sources of greenhouse gases. He is especially interested in the use of high-precision ground-based measurements that are sensitive to emissions on local to regional scales. Emissions can be quantified from these measurements using atmospheric transport models within a mathematical inversion framework. Developing novel measurement methods and improving the quality of information within this framework holds promise to reduce emissions estimate uncertainties and help focus climate change mitigation efforts.
