# 0. NEMO configurations #
The forced NEMO is available in its reference version with different configurations, two of which are used and updated jointly with the IPSL tools:
* ORCA2_LIM : a coupled ocean-sea ice configuration based on the ORCA (2° resolution) tripolar grid;
* ORCA2_LIM_PISCES : the ORCA2_LIM configuration described below and coupled with the marine biogeochemistry model PISCES.
To find out more about the model description and the reference configurations, go here: http://www.nemo-ocean.eu/About-NEMO
# 1. Retrieving NEMO and the reference configurations #
Two NEMO model versions are available with modipsl:
* the model version used to perform CMIP5: http://forge.ipsl.jussieu.fr/nemo/browser/branches/CMIP5_IPSL
* the latest version which can be compiled with FCM - starting from v3.3: http://forge.ipsl.jussieu.fr/nemo/browser/branches/2012/dev_v3_4_STABLE_2012

# 3. Running the model #
## 3.1 Input files: atmospheric forcings, initial states, namelists ##
The card files ( opa9.card for orca2_lim and pisces.card for pisces) contain the list of files needed to perform the simulation.[[BR]]
These files are described here: https://forge.ipsl.jussieu.fr/igcmg/wiki/DocImodelAnemo
## 3.2 The run ##
This example is a 5-year run of ORCA2_LIM [ ORCA2_LIM_PISCES ] splitted in 1-year jobs.
{{{
