Vacancy: Joint Research Professorship of SGO and FMI

At the Sodankylä Space Campus, a joint research professorship by Finnish Meteorological Institute and University of Oulu in Atmospheric Research and Imaging Applications is now open for applications.

Application deadline is 10 August 2018.

Sodankylä Space Campus

University of Oulu and Finnish Meteorological Institute jointly invite applications for the position of Professor in Atmospheric Research and Remote Sensing, with emphasis on Space and Imaging Applications. This is a joint Research Professor position between both institutes and is placed at Sodankylä. The position is filled at the level of Assistant Professor/ Associate Professor/ Professor, according to the qualifications and merits of the selected applicant.

The professor will work in the interdisciplinary research programs of the Sodankylä Space Campus and will participate as a supervisor in doctoral programs, related to the fields of sciences driven at the Sodankylä Space Campus.

Sodankylä Geophysical Observatory (SGO) is a separate research institute of University of Oulu, with a national task of carrying out geophysical measurements and related research. Research is both empirical and theoretical, including development of measurement methods and modelling.  SGO’s research of cosmic rays, magnetospheric physics, ionospheric physics and aeronomy of the middle and upper atmosphere belong to one of the strategic research spearheads of University of Oulu.

Finnish Meteorological Institute (FMI) operates at Sodankylä the Arctic Space Centre (FMI-ASC), which focuses on the Earth observation research and services, arctic climate change research and the development of weather-related intelligent traffic applications.

FMI and University of Oulu established in 2018 the Sodankylä Space Campus to enforce research co-operation by the two institutes at the Sodankylä Campus, in northern Finland.

FMI-ASC and SGO together operate a globally unique research infrastructure, providing integrated observations of the processes and couplings in the Earth-atmosphere-space system at high latitudes. Research at Sodankylä is carried out together with the wide international research community, based on utilisation and development of this infrastructure.

The new professorship aims to strengthen the joint research profile of the Sodankylä Space Campus targeted to atmospheric research, by applying these data for various applications in an advanced, more effective manner by taking full advantage of novel data inversion and assimilation approaches.

Tuleva revontulikausi

Klikkaamalla saa parempi kartta.
Meille tulivat jo ensimmäiset kysymykset milloin voidaan katsoa taas revontulet. Vastaus riippuu leveysasteesta. Etelässä pimeys palautuu aikaisemmin kuin pohjoisessa.

Kuinka pimeää pitäisi olla? SGO:n tieteelliset kamerat toimivat kun aurinko on vähintään 10° horisontin alapuolella. Toki on mahdollista nähdä erittäin kirkkaat revontulet jo ennen sitä.

Yllä oleva kartta näyttää minä päivänä aurinko on kesän jälkeen ensimmäistä kerta 10° horisontin alapuolella Suomessa. Kannattaa muistaa, että kesäaikana yön pimein aikaa on klo 01 ympäri.

Meidän tieteelliset revontulikamerat eivät ole vältämättä näinä päivinä alkamassa mittauksinsa operatiivisista syistä.

Start of the Northern Lights Season

Click on map for better resolution.

Almost three weeks after the summer solstice, we start to get questions regarding when the Northern Lights can be seen again after the Polar Day. The answer depends on where you are: the further south you are, the earlier it will get dark enough.

How dark does it need to be? Our scientific cameras operate when the Sun is at least 10° below the horizon. However, if there are particularly bright Northern Lights, you might be able to see them already earlier.

The map above shows the days on which the Sun will be at least 10° below the horizon in Finland. Be aware, however, that due to summer time (daylight saving time), the darkest time of the night is around 01:00h in Finland.

Note further, that our scientific cameras will not necessarily be back on location on the first day that it is dark enough. Their annual maintenance might well delay the schedule.
