Science objective of the ERG mission is to study acceleration and loss mechanisms of relativistic electrons around Earth during geospace storms.

SGO supports the mission by its ground-based measurement networks and collaborates closely with Nagoya University in interpretation of the satellite measurements by means of atmospheric modelling.

Recent joint study by Turunen et al., 2016 suggests that the so-called pulsating aurorae may associate energetic electron precipitation that is capable of remarkable ozone destruction in the mesosphere. By means of the ERG datasets, combined with the ground-based observations, we wish to study more closely this potentially important space weather influence on the upper atmosphere.

ERG/Epsilon-2 laukaisu tänään 20.12. klo 13

JAXA, (Japan Aerospace Exploration Agency) laukaisee ERG-tutkimussatelliitin 20.12.2016. Live-streamia laukaisusta voi seurata osoitteessa:


ERG-satelliitti tutkii Maan säteilyvyöhykkeiden suurienergisiä hiukkasia ja niiden käyttäytymistä magneettisten myrskyjen aikana. SGO:n, Ilmatieteen laitoksen ja Nagoyan yliopiston tutkijoiden yhteistyössä selvitetään sykkivien revontulien syntymekanismeja ja mitataan suurienergisen hiukkassateen aiheuttamaa pakotetta ilmakehään. Nagoyan yliopisto ja SGO ovat sijoittaneet Sodankylään uuden 100 kuvaa sekunnissa kuvaavan  revontulikameran tutkimuksia varten.

PhD Candidate in Radio Science and Ionospheric Physics

PhD Candidate in Radio Science and Ionospheric Physics at UiT The Arctic University of Norway

University of Tromsø - The Arctic University of Norway, Faculty of Science and Technology, has a PhD student position vacant for applicants who wish to obtain the degree of Philosophiae Doctor (PhD). The appointment is for a period of four years.

The successful candidate will participate in the development and use of novel high power large aperture radar observational techniques in combination with other relevant instruments, with the goal of advancing the state of knowledge of ionospheric phenomena. Examples of potential topics of research include: ionospheric modification, characterisation of auroral energetic particle precipitation, and magnetosphere-ionosphere coupling. The final scope of the thesis project will be determined based on the background and interests of the candidate.

The position is attached to the Space Physics group at the Department of Physics and Technology, which is located on the Tromsø campus of UiT. The Space Physics group has a long tradition in using the radar instruments of the EISCAT Scientific Association in Northern Scandinavia and plays an important role in preparing for the new advanced atmospheric radar facility EISCAT_3D. Scientists in the group also conduct research on topics including: auroral ionosphere, ionospheric modification, space weather, laboratory plasmas, space debris, planetary radar, dusty plasma in the mesosphere, and long-term trends in the ionosphere. The Space Physics group consists of eight faculty members and six PhD students. The group will be expanded by four PhD students and one postdoctoral scientist during the next year.

Further information about the position and project details is available by contacting:

Associate Professor Juha Vierinen, email juha-pekka.vierinen -at- uit.no or tel. +47 981 72 827.
