Introduction
NorESM1 is the Norwegian Earth System model used for CMIP5. The model is based on the CCSM framework (http://en.wikipedia.org/wiki/Community_Climate_System_Model). However, NorESM has special features developed by Norwegian researchers.
Main references are:
GMD - Special issue The Norwegian Earth System Model: NorESM; basic development, validation, scientific analyses, and climate scenarios
http://www.geosci-model-dev.net/special_issue20.html [1] [2] [3] [4]
This website contains information shared between NorESM developers and users.
Obtaining a version of the model
The development version has been moved to git: Obtain a copy through git clone https://githubUserName@github.com/metno/noresm.git You first need to be registered as a noresm user on github (see detailed info in Obtain a copy of the model (using git).
If you are on a normal ubuntu PC and want the source code, you might see that “svn checkout” complains about “gnome keyring”. If you see this problem, the solution is here: http://askubuntu.com/questions/206604/svn-and-gnome-keyring
Need access to other versions: Special access document:
Running / Configuring the model
Develop the model
Setting up at different machines
Most developers compile and run NorESM on hexagon (hexagon.bccs.uib.no). That machine uses the portland group fortran compiler. Most developers develop the code on that machine using “develop/compile/run/analyze print statments” on that machine.
Some experiments have also been done with compiling running CAM on a normal Linux PC in order to use interactive debuggers. (see below)
Issue tracker
Any development should ideally be agreed with the NorESM development team and be properly described in the issue tracker, see the link below
If you have changed the model and want to merge your changes to the trunk, your model has to pass some tests:

Version control best practices
- NEW: After switching to git (13th november 2015) the
svn-repository is read-only. Some advice on how to use the new git-repository are available here: Obtain a copy of the model (using git)

Archive model results
Long-term archiving is normally done on NorStore’s disk resources (e.g, in /projects/NS2345K/noresm/cases).
To avoid loss of data, another copy should be placed on tape. For instructions, see NorStore Tape Storage
Data that builds the basis of publications should be migrated to NorStore’s Research Data Archive in order to guarantee preservation and also to offload the project area. For specific NorESM instructions, see NorStore Research Data Archive: Guidelines for ingestion of NorESM output
CMIP5 archive of NorESM results
NorStore Research Data Archive: Guidelines for ingestion of NorESM output
Past and ongoing work
Several simulations have been performed with NorESM. A list of available simulations and runs can be found here. List of model runs by NorESM. The page also contains an overview of planned simulations. A fairly extensive description of the model and to some extent also the CMIP5 runs can be found at http://pcmdi9.llnl.gov/esgf-web-fe/

NorESM is also used in several projects: Existing projects
