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 :cite:`gmd-6-687-2013` :cite:`gmd-6-389-2013` :cite:`gmd-6-207-2013` :cite:`gmd-6-301-2013`
The next version of the model NorESM2 is built on a update version of the CCSM framework, CESM2. (http://www.cesm.ucar.edu/models/cesm2/) ; (https://en.wikipedia.org/wiki/Community_Earth_System_Model). Its aerosol module is based on OsloAero5.3 of NorESM1.2 / CAM5.3-Oslo :cite:`gmd-11-3945-2018`.
This website contains information shared between NorESM developers and users
- The development version has been moved to git: Obtain a copy through git clone https://[email protected]/metno/noresm.git You first need to be registered as a noresm user on github (see detailed info in :ref:`gitbestpractice`.
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

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)
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:
- 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: :ref:`gitbestpractice`
Some guidelines for modifying NorESM’s subversion repository: :ref:`svnbestpractice`
How-to for setting up svn repositories on NorStore: :ref:`svnnorstorehowto`

- https://github.com/metno/noresm/: featureCAM5-OsloDevelopment_trunk2.0-6 (Main development branch for CAM-Oslo aerosol features)
- https://github.com/metno/noresm/: feature-classnuc-ice_featureCAM5-OsloDevelopment-2 (ice nucleation feature branch)

- https://github.com/metno/noresm/: noresm-ver1_r112-r169/ (Further development from the CMIP5 version. Include EU-ACCESS project improvements)
You obtain the model code through checking it out. The command would be git clone https://[email protected]/metno/noresm.git git checkout -b aBranchName origin/aBranchName This gives the code in your directory
Developing the model also involves setting some uncertain numbers into the model. Not all of these are available from namelists. Go to the link below to understand where main uncertainties are.

Several tools are shared among NorESM users
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
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 :ref:`norstorearchive`
Model output and derived data products can be shared via the Norwegian Earth System Grid data portal http://noresg.norstore.no (see :ref:`norstoreesg` for instructions).
Some aerosol and cloud-relevant output for the development version of NorESM2 is available for those with MET Norway affiliation through VpN at /vol/fou/emep/People/alfk/CAM-Oslo-diagnostics/
Several simulations have been performed with NorESM. A list of available simulations and runs can be found here. :ref:`listofruns`. 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/
