During every single breath, we inhale thousands of tiny aerosol particles. Aerosol particles exist in the atmosphere all over the globe, also in the Arctic, where they play an important climatic role.

During his PhD studies, Robert Lange studied climate relevant properties of high Arctic aerosols. By measuring hygroscopic growth, cloud formation- and ice nucleation properties of aerosols at the Villum Research Station in northeastern Greenland, he quantified how these properties can influence the sensitive Arctic climate. His work also provided new insights into how human- and natural aerosols respectively influence the Arctic.

The new research findings contribute to the understanding of how aerosols are part of the Arctic climate system, and help constrain important climate variables that are still not fully understood.

The PhD degree was completed at the Department of Environmental Science, Science and Technology, Aarhus University.
