Hi Marco,

Great news! Thanks a lot for keeping me informed.

Update on the copyright status.

As of some weeks ago, the ocean model, BLOM/iHAMOCC, is free software (LGPL-3.0) [1]. The sediment burst-coupling code (GPL-3.0) will be incorporated into BLOM/iHAMOCC; permission has been granted by me to use my code under the terms of the LGPL-3.0 for this purpose.

The NorESM framework is licensed by default under BSD 3-clause licences, but there is a list of additional copyright terms for some parts of the code [2]. The burst-coupling code can also be run as part of BLOM/iHAMOCC without the NorESM framework (and using gfortran), hence by using exclusively free software.

Thank you!

(I will probably work on this further (pushing repo, homepage etc.) around the time of the preprint.)

Registration Administration

While this item will be useful to track the registration process, approving or discarding the registration must be done using the specific Group Administration page, accessible only to site administrators, effectively logged as site administrators (superuser):

Registration Details

  • Name: sediment burst-coupling in NorESM
  • System Name: burst-coupling
  • Type: Software
  • License: GNU General Public License V3 or later (The code has non-free dependencies. It will take time to clarify—and make free—all of this. I hope to be able to share my part already before all that has happened.)

Description:

This package contains the modified files of NorESM, especially the ocean biogeochemical component, necessary to execute long-term simulations of NorESM, the Norwegian Earth System Model, in a computationally reaonable time. In this the sediment is repeatedly decoupled and coupled to the ocean model (HAMOCC/MICOM). Through this, the ocean (seawater and sediment) is brought into a steady state.

http://klimato.org/pub/sediment_code-0.9.2.tar.gz

Other Software Required:
  • The NorESM framework, which should be that of CESM1.1 (using CIME);
  • a Fortran compiler.

Though standard Fortran 95/2003 is used (or so it is intended), it has only been compiled in its completeness (i.e. together with NorESM) with the proprietary Intel compiler (ifort).

Other Comments:

As of yet the model is not free software in its entirety. I keep on arguing at my university and our partners for that. It's a slow process, mostly because people need to be educated about free software.

I will publish a preprint of the corresponding study quite soon, so it will be useful to share the code (and development history) by that time.
