# OGGM Open Meeting

###### tags: `oggm` `meeting notes`

About the format of our meetings:
- **Flash updates** are a quick round of short updates (~2-3 minutes) by all parcipitants (please also write them in the shared notes). Here you can request for additional agenda items that require longer discussions (example: "I have a problem understanding XY")
- **Group agenda points** are longer, open discussion points of the day. This could be something that needs input from all participants, a discussion about model choices, or a prepared presentation from one of the members.
- Note that **our goal is to keep "Flash updates" + "Open agenda" under one hour** in order to keep a dynamic meeting.
- **Specific discussion:** more technical items that may not be of interest to everyone (e.g. about a specific problem, master thesis, etc.). These will take place after the official part.
- **Action items**: what needs to be done after the meeting and by who
- **Move to next meeting**: items that couldn't be discussed this time

### Flash updates
- Anouk:
- I'm currently working on global simulations over the period 0-2000 CE, forced with the Last Millenium Reanalysis. I'm in the phase of calibrating the simulations. In the end this experiment will serve as base simulation for the mass balance attribution to different climate forcings over the last millenium.
- Jan:
- Did some calibrated projections w/ and wo/ frontal ablation
- Can show some plots soon
- Julia:
- Coming to an end with my digression on carbon-cycle climate modeling
--> I would be happy to present some results about it (not OGGM related, but it is the prehistory and closely related to my following work with OGGM)
- will start global equilibrium runs with OGGM soon
- Larissa:
- Decision: recalibrating to Hugonnet for 2000 onward decades?
- Finishing all decades: can show plots next meeting?
- Patrick:
- Not much new, still working on connecting COMBINE with GlacierDirectories for testing the method on real glaciers
