Welcome to my homepage!

In my work I study meteorological, physical and chemical processes in the High Arctic. I am interested in dimethyl sulfide, DMS, a sulfur species that is produced by plankton in the oceans. DMS is transferred to the atmosphere via air-sea exchange at the surface. In the atmosphere the solar radiation break down (photo-oxidation) the DMS molecule. The oxidation products - such as methane sulfonic acid, MSA, sulfuric acid and sulfur dioxide can condense on pre-existing particles and thereby take part in cloud formation. DMS is one of the major contributers to the cloud formation in the High Arctic. Observations in the High Arctic have shown rapid changes (minutes to hours) in gas-phase DMS near the surface. The magnitude of these changes exceed the entire seasonal variability. I aim to investigate how important turbulence, advection and other meteorological processes are for the observed variability of DMS.

I am a Ph.D. student at the Department of Meteorology at Stockholm University, and I have a M.Sc. in Physics from Lund University. I did my master thesis at the Swedish Meteorological and Hydrological Institute in Norrköping, with the title "Evaluation of the SAFNWC/PPS Cloud Scheme in the Inner Arctic Using observations from the Arctic Oden Expedition in summer 2001". In 2006 I got married and changed my last name from Mattsson to Lundén.
