This repository contains the scripts used to implement a frontal ablation parameterisation into OGGM and produce the results of the paper submitted to The Cryosphere Disscus: Recinos, et al,. in review

This repository uses a OGGM version pinned to the following commit.

The content of the repository is the following:

I. cryo_cluster_scripts (scripts used in a cluster environment)

1. Columbia Glacier runs

2. Calving vs Volume experiment

3. Sensitivity experiments with OGGM default parameters: k, Glen A and fs

4. Alaska volume and volume below sea level calculated with different model configurations.

5. Marine-terminating glaciers frontal ablation fluxes calculated by correcting the depth and width of the terminus. (read Recinos, et al,. in review for more details).

6. Velocity experiment

• To run the scripts make sure you have this repository on the home directory of your cluster environment.

• To run the scripts you must follow the order of the folders.

• All scripts require a modified version of RGI v.6.0, where four Marine-terminating glaciers have been merged with their respective branches. This file is located here.

• RGI id's of the glacier merged:

RGI60-01.21008 with RGI60-01.26732
RGI60-01.10689 with RGI60-01.23635
RGI60-01.26736 with RGI60-01.14443
RGI60-01.03890 with RGI60-01.23664

• The merge was necessary in order to use McNabb et al. 2014 Terminus positions data base.

• Scripts in folders 2, 3, 4, 5 and 6 require the output of the Columbia Glacier pre-processing run. You can't run these folders without having ran the scripts in folder # 1.

II. cryo_plots (scripts for producing the figures)

• You will be able to run these scripts after you have completed the runs in cryo_cluster_scripts and copied to your PC home directory the output_data folder generated from the runs. The right path to copy this folder is in: ~/cryo_calving_2018/output_data/

Input data

• The input data to run all the scripts can be found here

Output data

• This folder will be generated once you have ran the first script of the folder cryo_cluster_scripts.
• Contains the output files for each folder in the cryo_cluster_scripts.

The rgi_overview.py requiere additional libraries outside OGGM libraries such as:
collections , cartopy, cartopy.mpl.gridliner , cartopy.feature, cartopy.io.shapereader and cartopy.crs
