About
A physicist’s curiosity. A climate scientist’s questions.
I am a climate scientist at the Nansen Environmental and Remote Sensing Center in Bergen, associated with the Bjerknes Centre for Climate Research.
One connecting thread
My work starts with a physical question and asks what observations and models can tell us about it. The setting has changed from the Martian atmosphere to Earth’s boundary layer, Arctic sea ice and local climate information.
What stays constant is an interest in quantities that can be checked, assumptions that can be examined and explanations that help other people use the evidence.
2009
Physics, planetary atmospheres and Phoenix
My PhD at York University in Canada focused on the Martian boundary layer and water cycle. Models and observations from NASA’s Phoenix lander helped establish how snow forms and falls in the Martian atmosphere.
2011 onwards
From planetary atmospheres to Earth’s climate
At NERSC, my work has connected boundary-layer meteorology to surface warming, temperature variability and climate-model evaluation.
Research today
Sea ice, local climate and useful evidence
I work across observations and models of the Arctic, northern urban climate and quantitative tools for exploring climate information. Counting Carbon extends that interest in inspectable calculations to carbon management.
Research leadership and collaboration
I have led ARIA and NERSC’s contribution to KeyCLIM, alongside collaborative work on sea-ice diagnostics, model development and climate information. The research pages bring together the questions, papers and collaborators behind this work.
