Division on Atmospheric Sciences (AS)

President: Annica Ekman,
Deputy President: Oksana Tarasova,

Atmospheric Sciences Division is one of the largest divisions in the European Geosciences Union. The research areas covered by division extend from the large-scale dynamical/meteorological processes and systems in the atmosphere (like cyclones and global atmosphere circulation) to the small scale turbulent mixing, they cover the time frame from centuries (in connection with climate research) to seconds (in the context of fast chemistry). Atmospheric Sciences include studies of the atmosphere composition, aerosol and cloud physics, gas-particles interactions and chemical reaction kinetics studied in the labs.


Obituary: Jón Egill Kristjánsson (1960 – 2016)

Jón Egill Kristjánsson, professor at the Department of Geosciences, University of Oslo, Norway, passed away in a tragic accident on the 14th of August, 2016. Born in Iceland, he moved to Bergen to study meteorology, where obtained his Ph.D. in 1991. After a post-doc at Los Alamos National Laboratory, he returned to Norway in 1993 and joined the University of Oslo, where he remained for the rest of his career. His principal field of research was cloud microphysics, aerosol - cloud interactions, and the optical properties of ice clouds. His contribution to atmospheric sciences includes major advances in the representation of cloud microphysics in climate models, with his co-developed parameterisation schemes being operational in the National Center for Atmospheric Research (NCAR) climate model since 2003 and later in the Norwegian Earth System model. He was moreover interested in polar lows and led the prestigious International Polar Year project The Observing System Research and Predictability Experiment (IPY-THORPEX) with several Arctic flight campaigns. The project lead to improved understanding and numerical representation of such explosive lows. In recent years his research path took a turn in the direction of climate geoengineering, with particular involvement in the development of the fields of so-called cirrus cloud thinning and marine cloud brightening.

Over the years Jón Egill became a leading international expert, known for his thorough and careful approach. His long standing high quality contribution to science led to the award of an honorary doctorate at the University of Stockholm in 2013. He enjoyed his extensive international collaborations, in particular with NCAR, where he visited on several occasions. He was dedicated and committed, with tremendous passion for his work, and always ready for a discussion. Jón Egill was greatly respected among the students; for his expertise, enthusiasm and ability to develop young talents into mature researchers.

He will be missed for his wide knowledge and academic leadership, not to mention his quick comments and laughter.

A new study published this month in The Cryosphere shows that all polar bear populations, found in 19 distinct Arctic regions, face a shorter sea ice season, with ice-covered days declining at the rate of 7 to 19 days per decade between 1979 and 2014. Other researchers, publishing in Earth Surface Dynamics, have investigated how the oxidation of sulfides in recent landslides drives intense weathering and how this process could be an important CO2 source. Meanwhile, a study in Biogeosciences reports observations to detect ocean carbonate chemistry outside preindustrial bounds to better understand ocean acidification impacts. Find out more about these and other studies published in EGU journals in the past month by following the links below.
