About
Dr. Rona Thompson is a senior scientist at NILU, Kjeller, since 2011.
Dr. Thompson has a PhD in atmospheric chemistry from Victoria University of Wellington, New Zealand. Since completing her PhD, Thompson has been a post-doc at the Max Planck Institute for Biogeochemistry in Jena, Germany, and at the Laboratory for Climate and Environmental Sciences in Saclay, France.
Dr Thompson’s main research interests are in understanding the sources and sinks of atmospheric pollutants, including greenhouse gases, and the processes driving these. For this, she employs atmospheric transport models and statistical methods.
Dr Thompson has a long experience working with, and developing, numerical models for atmospheric research. She is also the developer of the atmospheric inversion framework, FLEXINVERT.
Dr Thompson is actively involved in Norwegian and European research projects and is currently the coordinator of the Horizon Europe project, EYE-CLIMA. She is also the co-leader of the Global Carbon Project N2O Budget activity.
