My research group ATMOS (Synchrotron-based Atmospheric Science) aims to understand the importance of aerosols for various processes at the heart of atmospheric chemistry and global climate. We integrate a wide range of levels of complexity, from molecular characterization and interactions, to single aerosol particles and global responses to aerosol driven processes. At each stage, we use complementary experimental, theoretical, and computational approaches.

The core of our experimental research is molecular level characterization of atmospheric nano-particles and surfaces using synchrotron-radiation based spectroscopic techniques. Most synchrotron experiments are done at the new MAXIV facility (https://www.maxiv.lu.se/ ) in Lund, Sweden, which is now the world’s brightest synchrotron light source. This unique brightness gives us unprecedented opportunities to study properties of the aerosols and their surfaces in ways which have previously not been possible. For example, we can now get detailed chemical information about the molecules immediately on the surfaces of submicron water droplets. Our research unit NANOMO coordinates all Finnish national participation in MAXIV, where Finland is the second largest contributor.

In ATMOS, we have furthermore developed several models to simulate multiphase interactions in mixed aqueous organic aerosols. Ultimately, the global scale impacts of the aerosol processes we study are tested using some of the most comprehensive atmospheric chemistry and climate models in the world. Recently, we joined the EC-Earth consortium (https://www.ec-earth.org/ ) which already includes the Earth Systems Modelling group (http://blogs.helsinki.fi/esm-group/) from Helsinki University and Finnish Meteorological Institute.

Although our main focus is on aerosol effects in Earth’s atmosphere and their relevance for climate change, we are constantly working together with researchers from other fields to use our knowledge and methods in new and exciting ways. Current projects include such diverse topics as extraterrestrial atmospheres, effects of pathogens on tree growth, and industrial applications in materials sciences.
