Glacier Energy and Mass Balance (GEMB v1.0): A model of firn processes for cryosphere research
Nicole-Jeanne Schlegel
Eric Larour
Abstract. This paper provides the first description of version 1.0 of the open-source Glacier Energy and Mass Balance model. GEMB models the ice sheet and glacier surface-atmospheric energy and mass exchange, and firn state. It is a column model (no horizontal communication) of intermediate complexity that includes those processes deemed most relevant to glacier studies with the goal of retaining computational efficiency that can accommodate the very long (thousands of years) spin-ups necessary for initializing deep firn columns and for running sensitivity experiments to characterize model uncertainty on continental scales. The model is one-way coupled with the atmosphere which allows the model to be run off-line with a diversity of climate forcing but neglects feedback to the atmosphere. GEMB provides numerous parameterization choices for various key processes (e.g. albedo, subsurface shortwave absorption, and compaction), making it well suited for uncertainty quantification and model exploration. The model is evaluated against the current state-of-the-art and in situ observations and is shown to perform well.

Dear Juan,
Thank you for taking the time to provide us with feedback on our paper. The link (https://issm.jpl.nasa.gov/) in question is the project page for NASA's Ice-sheet and Sea-level System Model (ISSM), of which GEMB is the surface mass and energy balance module. ISSM has been open source since 2011 and is a complex multi-istitutional model that is fully open source but under Caltech copywrite. Moving the model outside of it's current location would be a major undertaking and may not even be possible. ISSM meets all of the GMD "Archive standards" for "Third-party archives" and the reviewers have open access to the code. Hopefully this alleviates some of your concerns even though we are not able to relocate the model.
Sincerely,Alex

Hi Juan,
Looking at past ISSM papers in GMD they have included statments similar to this:Code Availability: GEMB is a module implemented inside of ISSM. The code can be downloaded, compiled, and executed following the instructions available on the ISSM website: https://issm.jpl.nasa.gov/download (last access: June 1, 2022). The public SVN repository for the ISSM code can also be found directly at https://issm.ess.uci.edu/svn/issm/issm/trunk (Larour et al., 2022), and can be downloaded using username “anon” and password “anon”. The version of the code for this study, corresponding to ISSM release 4.19, is SVN version tag number 27035.

We will make sure to include this in the next round of revisions.

Dear authors,
Thanks for the quick reply. Unfortunately, we can not accept your explanation of the potential complexity or impossibility of sharing the code outside Caltech servers. This, at best, sounds like an apology for not undergoing the effort to share the code in a valid repository. What technical complexity explains why it can not be deposited in an external repository? That is, we need the technical details about what makes it impossible to assess if such motivation is acceptable.
Also, you mention a previous paper with the same code published in our journal. Thanks for pointing it out. Could you provide the details of the paper to consult it? It could be a long process for us to look at the entire database of published papers looking for the one with such a Code Availability section.

Dear Juan and Authors,
First, thanks to Juan for catching this; I had not realized that the NASA repository was not in compliance with GMD standards.
Second -- and not to sidetrack the current request regarding the other paper, which seems valuable in its own right: Would another possibility be for the source code to GEMB to be made fully available (e.g., on GitHub)? This is not a situation that I have encountered before, but I believe that GMD allows open-source code in closed-source frameworks to (e.g., with Matlab). In this case, perhaps an open-source code in a not-GMD-standard open-source framework would do?
I hope that we can find a smooth solution, and I also do wonder if there could be long-term benefit (likely beyond the scope of this submission) in ISSM moving into a more mainstream open-source access and archiving framework.
Best wishes,
Andy Wickert

Dear editors,
Thank you for your discussion on this topic. While we and the ISSM work for a solution to your concerns so our publications can move forward, I think it is important to specifically and officially clarify in this discussion that the public version of ISSM is not archived on a NASA server. To be more precise, as Dr. Gardner pointed out earlier in comment AC2, ISSM is archived on an open-source svn server at the University of California, Irvine (UCI), at https://issm.ess.uci.edu, and has been since 2011. The confusion may be that the ISSM homepage itself and other ISSM helpful model documentation is archived on a NASA server (https://issm.jpl.nasa.gov).
We realize that the UCI server in question may still not be in compliance with your open-source policy (?), and in that case, we will continue to work towards a solution that is acceptable to GMD.
Thank you, Nicole Schlegel

Dear authors and Andy,
GitHub is not valid. Indeed, storing code on Github is by far the problem that accumulates the most violations of code publication policies in scientific research, or at least in our journal. You have to understand that GitHub is a product of a company (Microsoft) that could decide to terminate its service at any point and delete all the material stored there. Our policy (and policies should be read before submitting manuscripts) states it clearly, and what is more, GitHub says on its web page that it is not a service that can be used for long-term archival:"Project or institution websites and online revision control sites such as GitHub11, GitLab12 or Bitbucket13 are made for code development but unsuitable for archiving frozen code versions."https://www.geoscientific-model-development.net/policies/code_and_data_policy.html#item3To qualify as a suitable long-term archival for scientific publication, a repository needs to be funded for the next 10-20 years at the minimum and regulated by bylaws that show the commitment for perdurance along time. Again, our policy provides a list of suitable ones.In your case, if moving the code to GitHub is easier from the technical point of view, I recommend moving it there and then using the Zenodo-GitHub integration (functionality provided by GitHub) to store a copy in Zenodo. Zenodo is one of the acceptable repositories. I hope this helps.Again, please, give me the details about which is the paper you have mentioned before. We need to check it to maintain coherence for all the submitted and published manuscripts.Regards,Juan

Dear Editors,
We are working to archive a static copy of the current version of ISSM on an acceptable third party server. The latest maintained model will remain in UCI servers for the time being so we will still encourage readers to look there if they're interested in the latest version of ISSM.
Given that the code is publicaly accessable for the reviewers to inspect, I wonder if we can start the review process while we archive a static copy of the code on a third party server.
For reference here is the list of 11 publications of ISSM already published in GMD.

Dear editors,
The frozen version of the source code for ISSM v4.21 has been archived at https://doi.org/10.5281/zenodo.7026445 . This should satisfy the archiving requirement. We will update our code availability statement accordingly.
We have many ISSM publications in GMD, as Dr. Gardner has listed in his latest post. You can also access a full list of publications at: https://issm.jpl.nasa.gov/publications/ .
Thank you for your guidance in this matter,

Dear authors,
Many thanks for your reply and for storing the code in Zenodo. We can consider the problem solved.
Regarding your previous question about beginning the review process as the code is available to reviewers, our policy mandates that a paper can not even be published in Discussions if it does not comply with the code and data availability statements. Therefore, the fact that your manuscript is already in Discussions was an oversight by our side, so there was no point in inviting reviewers. However, now that the issue with the ISSM code has been fixed, we can proceed with it.Regards,
Juan A., Añel

Dear Juan,
Indeed, I intended to note the Zenodo integration of GitHub for storage there, with GitHub being a good tool for updating and re-archiving (at Zenodo) should a need for updates arise in the review process, as they often do. My apologies for the lack of precision; I was responding in the midst of an international move.

We are working to archive a static copy of the current version of ISSM on an acceptable third party server. The latest maintained model will remain in UCI servers for the time being so we will still encourage readers to look there if they're interested in the latest version of ISSM.
Given that the code is publicaly accessable for the reviewers to inspect, I wonder if we can start the review process while we archive a static copy of the code on a third party server.
For reference here is the list of 11 publications of ISSM already published in GMD. We note that our software has long-term support and has been hosted at UCI for the past 14 years and is publicaly accesable.- Bulthuis, K., & Larour, E. (2022).

Dear editors,
The frozen version of the source code for ISSM v4.21 has been archived at https://doi.org/10.5281/zenodo.7026445 . This should satisfy the archiving requirement. We will update our code availability statement accordingly.
We have many ISSM publications in GMD, as Dr. Gardner has listed in his latest post. You can also access a full list of publications at: https://issm.jpl.nasa.gov/publications/ .
Thank you for your guidance in this matter,
Nicole Schlegel

Dear authors,
Many thanks for your reply and for storing the code in Zenodo. We can consider the problem solved.
Regarding your previous question about beginning the review process as the code is available to reviewers, our policy mandates that a paper can not even be published in Discussions if it does not comply with the code and data availability statements. Therefore, the fact that your manuscript is already in Discussions was an oversight by our side, so there was no point in inviting reviewers. However, now that the issue with the ISSM code has been fixed, we can proceed with it.Regards,
Juan A., Añel

Dear Juan,
Indeed, I intended to note the Zenodo integration of GitHub for storage there, with GitHub being a good tool for updating and re-archiving (at Zenodo) should a need for updates arise in the review process, as they often do. My apologies for the lack of precision; I was responding in the midst of an international move.
Andy
