Summary of SOTERIA Event workshop 2009
Goal
One important strength and attraction of the SOTERIA consortium is the wide range of expertise of the partners, ranging from the sun through the heliosphere and magnetosphere to the ionosphere, and also from observations to modelling and data assimilation. The idea behind the workshop was to build on this diversity to support the activities and foster new ideas.
The main goal of the workshop was thus to strengthen cross collaborations between the SOTERIA participants, to support already ongoing projects and to initiate new collaborative projects.
The new collaborative projects was intended both as new projects between the WP4 participants, but also as new collaborations across working packages, in particular between WP3 and WP4. Combining the expertise of these two work packages would allow to commonly study eruptive events from their origin at the Sun to their arrival and impact at Earth as well as to study the impact of the coronal to interplanetary structures on CME propagation.
Organization and Participating partners
The workshop took place in the period September 13.-18. 2009 in Hvar City in Croatia. The program was organized in close collaboration between DTU and HVAR. The local organization was undertaken with large effort and dedication by HVAR, and with overwhelming support by local residents and authorities of Hvar City.
18 persons participated in the workshop, mostly from institutions participating in WP4. The following institutions were represented: HVAR, UNIGRAZ, NOVELTIS, UOulu, MTA-KFKI-RMKI, IEEA, FIAN, KU Leuven and DTU. The wide range of competences within SOTERIA was well represented, and the participants constituted a balanced mixture of experienced researchers and ph.d. students within the consortium.
Activities
The starting point for the workshop was an ongoing collaborative effort to gather and exchange data and modelling results on a set of specific space weather events (CME’s at the sun or magnetic storms at the Earth). One particular event, occurring in late July 2004, was selected to initiate the discussions and allow the participants to present their competences and interests. The presentations of the different aspects of the same event, i.e. different forms of observations, data interpretation and modelling, was quite effective in identifying research subjects of common interest where the participants could support each other in the SOTERIA investigations, and also in generating new ideas on collaborative projects.
The form of the workshop was discussions and work in subgroups, alternating with discussions and presentations in plenum. The discussions where started in so-called MFE groups (“main field of expertise groups”) within the fields: Sun – Heliosphere and Magnetosphere - Ionosphere. In the later parts of the meeting the main discussions were, however, conducted in newly formed “collaborative projects groups”.
In addition a number of plenum discussions on specific subjects, so-called round-tables, where conducted. These were effective both for exchange of knowledge and to generate ideas. The round-tables also fulfilled a need for room to ask and answer basic questions. This was necessary due to the wide spread in competences in the group, both with respect to experience but also with respect fields of expertise. Round-tables were conducted on the following subjects:
- What is geo-effectiveness?
- CME structure
- Coronal holes and CIR’s
- Data assimilation into modelling
- Difference between CME- and CIR-generated storms
Outcome
The workshop was considered very fruitful by all participants, and was highly successful in achieving the stated goals.
The most important outcome was the formation of a large number of “Collaborative projects groups” listed below. Some of these were formed to support already existing initiatives or work in separate institutions, but a significant part concerned new projects. For each project a coordinator/main responsible was identified. Concerning the new projects, some were started at the meeting, and some were planned to start working later.
Another important outcome was common decisions concerning the future form of the collaboration and communications.

Future meetings and communications:
It was agreed that the work would be continued in the individual project groups, but that regular communications involving the entire group would be desirable. Two means of communications were foreseen, future meetings and regular telecons. In addition a list of phone numbers and e-mails of participants were created and circulated at the meeting.
Meetings decided in addition to already planned SOTERIA events:
- An extra day at the Davos meeting devoted to project group discussions will be pursued
- Project group meetings for participants at ESWW, will be planned by project group leaders
- A new workshop in 2010 to support the work in the formed project groups are planned
- IUGG/IAGA is an important world-wide conference covering all the science topics from the Sun to the Earths ionosphere and was therefore considered a good candidate for presentation of the main results of the collaborations in 2011. In addition a SOTERIA (WP4) Splinter at this meeting is planned.
Telecons:
It was decided to conduct bi-monthly telecons in the group. Skype will be used as first experiment, and will be installed by all participants. The first telecon will take place 1 month after the workshop.
