# 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

### Flash updates

- Patrick:
- new version of filter_inversion_output merged
- with this now prepro runs with semi-implicit model possible
- worked on glacier gallery (OGGM-Edu app)
- working on my PhD-Concept presentation

- Julia:
- concerning the equlibrium runs, we will concentrate on the Alp for now (because of the past tidewater problem)

- Fabien:
- overhaul of OGGM-MB is happening! Big changes incomming
- OGGM - IGM link prototype
- GLAMBIE workshop yesterday: https://glambie.org/workshop-1/
- Lily is working on GlacierMiP 3 in Zürich
- \> 300 applicants for the Pakistan training
- Paper from Regine is finally out: https://doi.org/10.1017/jog.2023.1

- Jan
- Working on code to be mergeable into the OGGM master

- Samar
- Still doing some test runs in HMA sub-domains with CISM, before GlacierMIP3 submissions
- OGGM-Karakoram paper is with editor after reviews - likely revisions coming soon (hopefully not rejection)

- Lizz (+ Molly)
- Intercomparison: we have old runoff projections from Erik, starting in 2020...planning new ones?
- Molly running multi-GCM projections for La Paz glacier runoff
- Modifying precipitation (move mean) directly is difficult - should we modify during the bias correction?
- Modify the reference climate, and/or modify the precip scaling factor (multiplicative change is more common than additive anyway for this application)

### Group Agenda Points

- optimise OGGM runs on cluster (discussion)
- trivial solution: batch of 100 or 1000 glaciers instead of RGI regions. Easy to implement, only drawback is that aggregation back into RGI region files happens after the run (but is trivial using xarray).
- restart runs: harder solution. Having a queue system which checks when a previous run is done and starts again (like with WRF). This needs Timo's help.

### Questions

# Call: 2023-01-25 10:00-11:00 CEST

### Flash updates
- Jan:
- Resubmitted frontal ablation paper and now working on ocean data again

- Patrick:
- still working on filter_inversion_output
- small adaptations of glacier gallery (OGGM-Edu app)
- working on PhD concept

- Nicolas:
- new internship on using Julia langage (ODINN) into OGGM
- work with Hamid on parameter perturbation experiments into PROTECT project

- Anouk
- I encountered an issue with my .slurm script. Commenting out, pip install --upgrade pip setuptools, made the script run again (at least for now, this not a permanent solution, but might be helpfull when wanting to run and old script ;) ). See the cluster-Bremen channel for more details.

- Lily:
- did some visualisations of Rounce et al. (2023) data
- working on a review, AGM presentation, manuscript, made my code publicly available

- Fabi:
- Meeting with Gerard Roe, Daniel Otto, Ben and Anouk: attribution using OGGM Project
- Meeting with Guillaume Jouvet for the OGGM-IGM link
- New OGGM-Edu notebook: [ice_on_incline](https://oggm.org/oggm-edu-notebooks/oggm-edu/ice_on_incline.html). OGGM-Edu working well on classroom.oggm.org
- Still making plans and trying to delegate some work for OGGM 1.6
- RGI: https://glims-rgi.github.io/user_guide

### Group Agenda Points
- Lily presents updated OGGM-edu app of glacier projection changes with the Rounce et al. (2023) data
- [Alpine glaciers](https://cluster.klima.uni-bremen.de/~lschuster/rounce_2023_data/0_exploratory_data_analysis/alps_future-app_rounce_ssp_en.html)
- [Global glaciers](https://cluster.klima.uni-bremen.de/~lschuster/rounce_2023_data/0_exploratory_data_analysis/global_future_glacier-app_rounce_en.html)

### What has been discussed the previous meeting, the most important points.
Jan gave a presentation on "OGGM-Nemo interactions".

### General Announcements and reminders
- Science Cafe
- Feel free to suggest/organise a Science Cafe, by e.g. inviting a speaker or suggesting a paper to discuss.
- Madlene started her simulations, using 21 nodes for the next couple of months.

### Flash updates

- Lily
- submitted abstracts to AGM and EGU, applied to Karthaus summer school
- worked on my discussion & conclusion part of my paper, deadline for annals of glaciology where I want to submit got extended (until end of February)
- currently downloading Rounce et al., 2023 data for some exploratory data analysis. If you need it -> it is here: https://cluster.klima.uni-bremen.de/~lschuster/rounce_2023_data/ , will add some example notebooks
- Patrick
- working on filter_inversion_output
- included/adapted SemiImplicitModel in COMBINE
- started the implementation of real glaciers to the glacier simulator on OGGM-Edu
- presentation about the future of glaciers in Ötztal tomorrow
- Anouk
- The following paper, I'm co-author on, got published: [Regional and tele-connected impacts of the Tibetan Plateau surface darkening](https://doi.org/10.1038/s41467-022-35672-w).
- EGU abstracts
- OGGM-Edu: an open-source educational platform about glaciers and glacier modelling
- The influence of climate forcings on global glacier evolution over the last millennium
- Simulations
- Hamid
- Submitted abstract to EGU 2023
- latin hypercube sampling for PROTECT project
- Samar
- Initial runs with CISM on a 200-m grid for the Everest domain - results look good
- Preparing the set-up for GlacierMIP runs (still aiming for GlacierMIP3)
- Larissa
- Submitted paper to AoG
- Almost done with revisions for decadal paper
- Thesis writing (Niels Bohr Institute April 1st)
- Fabien
- EGU abstract to the overshoot session (10 abstracts, 80-90% from PROVIDE)
- I started to dig into Jan's code, which tbh is quite some work
- Thank you for pointing out the issues on our Science paper

### Group Agenda Points

- OGGM developments in the making -> 1.6
- Prepare gdirs which allow to use the new solver
- Calibrate the mass-balance model and allow to calibrate
- GlacierMip3 with frontal ablation

### Questions

- Samar: shapefile to raster and 200-m netcdf grid - projection issues?
