OGGM - PyGEM Global Glacier Modeling Workshop 2022

16 - 21 September, Finse, Norway

Posted by Anouk Vlug, Regine Hock, David Rounce, Fabien Maussion and Ben Marzeion on May 9, 2022

What is it ?

The workshop is the 6th in a series that has brought together the community of users and developers of the Open Global Glacier Model (OGGM). This year’s workshop is organized jointly with the Python Glacier Evolution Model (PyGEM) community. It is open to anybody interested in global glacier modeling with focus on active developers and users of OGGM or PyGEM. The primary goal is to discuss the challenges and solutions in modeling glaciers at large scales, to learn from each other, and to develop ideas and visions for the advancement of such models. The workshop will include scientific presentations, hands-on coding sessions, discussion/brainstorming sessions, and generally be held in an informal manner (with a possible hike to a nearby glacier).


The workshop will include:

  1. Scientific presentations by the participants (ca. 15-20 min) on topics related to the theme of the workshop. These can include the state, recent developments and results of large-scale glacier modeling.
  2. Discussion/brainstorming sessions focused on topics of interest, such as future developments and visions for global glacier models.
  3. Hands-on sessions in smaller groups including:
    • Beginner tutorials: these sessions are for current and future OGGM/PyGEM users to learn how to set-up and customize a model run.
    • Advanced tutorials: on topics such as How to contribute to OGGM/PyGEM, use OGGM/PyGEM with your own data, or use parts of OGGM/PyGEM with another model.
    • Q&A session: on model problems and possible solutions.
  4. Glacier excursion: Weather and snow conditions permitting we also plan a ½ day excursion to one of the nearby outlet glaciers of the Hardangerjøkulen Ice Cap.

We like to keep the schedule flexible in order to meet the needs, interests and suggestions of the participants. Tentatively, we plan to have presentations mostly in the mornings and group discussions and hand-on sessions in the afternoons.

Who can participate ?

Anyone working on large-scale glaciological modeling, in particular using OGGM or PyGEM, but also any other global glacier modeler keen on learning more about OGGM/PyGEM! In particular, we would like to encourage model users (current and future) as well as model developers to join us. The number of participants is limited to approximately 30 due to the housing limitations at the Finse Research Center. Therefore users and developers of OGGM or PyGEM will be given priority in case interest exceeds capacity.


The workshop will be held at the Finse Alpine Research Center run by Oslo and Bergen University. The station is located near the >70 km2 Hardangerjøkulen Ice Cap with one of the outlet glaciers only a couple of km away and well visible from the Research Station. Finse is a tiny mountain village with only a few houses located at the Oslo - Bergen railroad at 1,222 meters (4,009 ft) above sea level, about 250 m above the treeline. There is no road to Finse. Facilities are very limited, e.g., there is no grocery store, pharmacy or bank. In mid September the weather can be highly variable. Air temperatures may fall below freezing and heavy snowfall may occur combined with high winds.


Finse is only accessible by train, from either Oslo central station (Oslo S) (ca. 4.5 hrs; ca. 6 trains per day between ca. 6:00 and 23:00; ca. 600 NOK one way) or Bergen (ca. 2.5 hrs). Tickets can be bought at www.vy.no. From the Gardermoen Airport, Oslo central station can be reached by train in 20-30 minutes (many trains per hour). From Finse train station it is a 15-20 minute walk (ca. 1.5 km) along a small dirt road/hiking path to the research station (which may be snow-covered at that time).

Arrival / departure dates

The workshop starts at Finse on 16 September with dinner and ends on 21 September after breakfast. The Research Station closes on 21 September for winter, therefore one needs to leave the facility latest in the early afternoon on that day. Thus we recommend all participants flying into Oslo Gardermoen to land 16 September in the morning and book a return flight not earlier than late afternoon on Sept. 21.

Accommodation / meals

All participants will be housed at the Finse Research Station which has a number of 2-4 bed rooms which participants will share. We will be the only group at the station at that time. A cook at the station will provide all meals for the workshop. The station has a lecture hall and internet (4G eduroam and University of Oslo guest login).

Workshop fee

The final workshop fee is not confirmed yet, but we anticipate ca. 250 NOK/person/night for accommodation and ca. 900 NOK/person/day for meals.


If you wish to participate in the workshop, please fill out the following form. Due to the limited capacity of the workshop location, we would kindly like to ask you to do so before 31 May (indicating your interest does not mean you’re registered right away for the workshop). If you have any questions please send an e-mail to info@oggm.org.
