Space physics from University of Helsinki gets its first-ever International Space Science Institute team
Lucile Turc to work on mystery waves that transmit in the near-Earth space.
For the very first time space physics at University of Helsinki gets an International Space Science Institute (ISSI) team. It is Marie Curie Fellow Lucile Turc that will head an international space science team to investigate one of the great mysteries in space physics that has been under research for a long time without any answers. There has not been enough data or good enough models to do that, so far.
”This mystery is about how some electromagnetic waves travel through our near-Earth space, while no one knows why and how. We know where these waves come from, a very turbulent region just beyond the magnetic bubble formed by our planet’s magnetic field. We know that these waves somehow enter our magnetic bubble, because we observe them in there, and even at the Earth’s surface. But what happens in between has so far eluded us. These waves are critical e.g. in understanding the radiation environment,” Lucile Turc says.
Vlasiator code can describe the processes from which the waves originate
In the recent years, more and more scientific spacecraft have collected data in the different regions of near-Earth space. Also, novel supercomputer models, such as the Vlasiator code developed at the University of Helsinki, can now describe the small processes from which the waves originate in their global context, the whole near-Earth space.
Combining these measurements and modelling tools now makes it possible to track the waves throughout their journey towards the Earth, but requires a wide-ranging expertise.
“That’s where the ISSI team comes into play: it brings together scientists from different background, to finally solve the mystery of the waves’ propagation,” Lucile Turc says.
The International Space Science Institute (ISSI) is an organisation for a deeper understanding of the results from different space missions, ground based observations and laboratory experiments worldwide. The setting is multi- and interdisciplinary, and to foster international networking, the institute selects, after a highly competitive evaluation, international teams to reach out for new scientific horizons.
“To get an ISSI team means that the team leader may gather a group of exceptional international scientists from all over the world to work with,” Professor Minna Palmroth of University of Helsinki explains.

The glacier in Basin 3, Austfonna Ice-cap, Svalbard, is moving faster than before – summer melt water could be one of the causes7.2.2018 16:07 | Tiedote
Numerical simulations provide a way to link the melt at the glacier surface to the hydrology system at the glacier bed to explain the surge in Basin 3, Austfonna Ice-cap, Svalbard. This is shown in a fresh doctoral thesis on ice flow modeling of ice shelves and ice caps by Yongmei Gong from the University of Helsinki.
New methods to estimate rainfall and how icing affects wind energy29.1.2018 16:19 | Tiedote
Accurate meteorological analysis products merge information from various observation instruments a new study shows. Erik Gregow is defending his doctoral thesis on February the 9th at the University of Helsinki. He found out that thunder lightning information is useful when we need to estimate the rain amount; he also presents new modelling results on how icing affects the wind energy.
