Developers doing research resulting in presentations or papers agree to the following procedures with regard to co-authorship:
- Users of CESM development code must offer co-authorship (or other mutually agreed upon recognition) on papers, conference abstracts or other scientific communications to the contributors of CESM development code named in the code if the following three conditions all apply:
- The research utilized the code by invoking it at run time
- Not utilizing the code would change the results and/or conclusions
- At the time the code was first utilized, it had not yet been publicly released
- Developers may not redistribute code to anyone outside of a research group.
- Any Developer doing research using a developmental version of the model that results in presentations or papers should document their experiments in the experiments database (or provide similar documentation through another means) and provide the High Performance Storage System (HPSS) location of the history files used in the presentation or paper. If the source code used in the experiments is not available through the Subversion repository, it should be made available to the development team for checking back into the CESM code repository.
To avoid violating this policy, Developers working with unreleased code should contact the co-chairs of the relevant working group(s)before beginning any work with unreleased and unreferenced code. Failure to abide to the above policy will lead to developer's access being revoked.
Repository Access Policy
Repository usage is monitored and access will be terminated if any terms of the access policy listed below are violated.
CESM uses Subversion and Github as tools for source code control. Development occurs only within specific component directories. Within each component directory, there is one main trunk and multiple branches. Branches can be created from any point in the repository and can be merged together at any point in the repository. Under this policy, collaborator development is allowed only on branches and under no circumstance should any developer commit changes to the main trunk unless specific permission is granted by a working group co-chair. The trunks are reserved for formal component releases (staged, internal, or external).
Developers are allowed to create branches off their own branches and are allowed to work on multiple branches and update or merge codes from other branches as long as permission to access all those branches has been formally granted. In general, development versions should be kept up to date by the Developer with the latest version on the main trunk. Before a Developer's branch is merged onto the main trunk, the Developer must make a request to the working group co-chair; the component must pass certain testing and validation criteria; the Developer must show scientific or software benefits; the branch version must be consistent with the latest release on the main trunk; and the change must be approved by the relevant working group co-chairs.
Source code from the repository will only be used for the agreed upon code development project and may not be used for any projects outside the scope of the agreed upon project.
- Who are developing code under the direction of someone with repository access
- Who are working on the same tasks as those described in the repository request
- Whose work is supervised by the primary developer
No other sharing of development code is allowed and the Developer may not extract code from CESM Development versions for inclusion in other models.

CESM/HOMME Development Code Repositories Access, Renewal and Update Forms
- New Access Request
- New access requests require CESM working group co-chair and CSEG approval. You will also be required to provide the name of a NCAR staff member who can vouch for your work.
CESM / HOMME Development Code Repository Access Request Form
- Renew Access
- Expired users can use this form to request a renewal of their account. You will still be required to input your CESM SVN developer's credentials in order to access the form. Renewal requests also require CESM working group co-chair and CSEG approval. You will also be required to provide the name of a NCAR staff member who can vouch for your work.
