# OGGM cryo calving paper 2019



This repository contains the scripts used to implement a

frontal ablation parameterisation into [OGGM](www.oggm.org) and produce the 

results of

the paper submitted to The Cryosphere Disscus: 

[Recinos, et al,. in review](https://doi.org/10.5194/tc-2018-254)



This repository uses a OGGM version pinned to the following [commit.](https://github.com/OGGM/oggm/commit/8ff54d5d0a3549a1e94ec31d246094f7dbd80c1e)



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](https://doi.org/10.5194/tc-2018-254) 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](https://cluster.klima.uni-bremen.de/~bea/cryo_calving_input_data/).**  



* 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](https://cluster.klima.uni-bremen.de/~bea/cryo_calving_input_data/)



**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.



#### Please read the top of the scripts to know more about the ouput of each run.



## External libraries that are not in the OGGM env:    



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`
