How to install ORCHIDEE in coupled mode with LMDZ
Author: J. Ghattas
Last revision: 2023/11/30, J. Ghattas
There are different predefined configurations in modipsl containing LMDZ and ORCHIDEE. Different configurations are adapted to different versions of the modeles.
- IPSLCM7_work : Working configuration for the next coupled model under development. It contains both ORCHIDEE_2_2 and ORCHIDEE trunk, the choice is done when compiling. It is possible to extract a sub-configuration such as LMDZOR or ICOLMDZOR.
- LMDZOR_v6.4_work : Working configuration which uses the latest revision of ORCHIDEE/trunk. The version of LMDZ is the same as in LMDZOR_v6.2, and compilation is the same as for LMDZOR_v6.2_work. Only ORCHIDEE version differs between the two.
- LMDZOR_v6.3_work : Working configuration which uses the latest revision of ORCHIDEE_3 branch (version copied from the trunk including nitrogen cycle). The version of LMDZ is the same as in LMDZOR_v6.2, and compilation is the same as for LMDZOR_v6.2_work. Only ORCHIDEE version differs between the two .
- LMDZOR_v6.2_work : Working configuration which uses ORCHIDEE_2_2 and LMDZ6/trunk.
- LMDZOR_v6.1.X : Configurations used for CMIP6 production simulations using stable versions of LMDZ and tag ORCHDIEE_2_0, read more about LMDZOR_v6. Take the highest number of X (currently LMDZOR_v6.1.10).
- (Obsolete LMDZOR_v5 : Contains a trunk version 2076 of LMDZ5 and ORCHIDEE tagged version 1.9.5 (CMIP5 version))
- (Obsolete LMDZOR_v5.2 : Contains the same LMDZ5 as LMDZOR_v5 and revision 2247 on the trunk of ORCHIDEE)
Usage of these configurations are covered by the igcmg_doc documentation : https://forge.ipsl.jussieu.fr/igcmg_doc/wiki/Doc
Quick summary for installing IPSLCM7_work for mode LMDZ-ORCHIDEE
For all configuration in the generation v7, IPSLCM7, only one fully coupled configuration exist. Using this configuration, it is possible to install a sub-configuration with only the parts you want. For example a sub-configuration is ICOLMDZOR containing DYNAMICO, LMDZ and ORCHIDEE. This sub-configuration can be used on the icosahedric grid or on the regular lat-lon grid. Another sub-configuration is LMDZOR which can only be used on the regular lat-lon grid.
With this configuration, both ORCHIDEE_2_2 and ORCHIDEE trunk (called ORCHIDEE_4) are downloaded but only one is compiled. Currently by default it is ORCHIDEE_2_2 which is compiled. You can add -orch4 to compile ORCHIDEE trunk instead. A suffix v22(for ORCHIDEE_2_2) or v4(for ORCHIDEE trunk) is added to the name of the executable, see folder modipsl/bin.
svn co http://forge.ipsl.jussieu.fr/igcmg/svn/modipsl/trunk modipsl cd modipsl/util ./model IPSLCM7_work LMDZOR cd ../config/IPSLCM7
To compile ORCHIDEE_4(trunk) add argument -orch4:
./compile_ipslcm7.sh -orch4
To compile ORCHIDEE_2_2, this is the default:
./compile_ipslcm7.sh
Quick summary for installing IPSLCM7_work for mode DYNAMICO-LMDZ-ORCHIDEE
For all configuration in the generation v7, IPSLCM7, only one fully coupled configuration exist. Using this configuration, it is possible to install a sub-configuration with only the parts you want. For example a sub-configuration is ICOLMDZOR containing DYNAMICO, LMDZ and ORCHIDEE. This sub-configuration can be used on the icosahedric grid or on the regular lat-lon grid. Another sub-configuration is LMDZOR which can only be used on the regular lat-lon grid.
See here how to install the sub-configuration ICOLMDZOR:
svn co http://forge.ipsl.jussieu.fr/igcmg/svn/modipsl/trunk modipsl cd modipsl/util ./model IPSLCM7_work ICOLMDZOR cd ../config/IPSLCM7 ./compile_ipslcm7.sh
With this configuration, both ORCHIDEE_2_2 and ORCHIDEE trunk are downloaded but only one is compiled. Currently by default it is ORCHIDEE_2_2 which is compiled. You can add -orch4 to compile ORCHIDEE trunk instead. A suffix v22(for ORCHIDEE_2_2) or v4(for ORCHIDEE trunk) is added to the name of the executable, see folder modipsl/bin.
Quick summary for installing LMDZOR_v6.4_beta
Use the same method for LMDZOR_v6.3_work or LMDZOR_v6.2_beta.
svn co http://forge.ipsl.jussieu.fr/igcmg/svn/modipsl/trunk modipsl cd modipsl/util ./model LMDZOR_v6.4_beta cd ../config/LMDZOR_v6 ./compile_lmdzor.sh
Compilation is done for a default horizontal grid and using compile option for production mode. The default settings can be changed optional arguments. Access to the help using ./compile_lmdzor.sh -h.
Quick summary for installing LMDZOR_v6.1.10
This configuration and older once are compiled using Makefile. More recent configurations uses a compilation script instead.
svn co http://forge.ipsl.jussieu.fr/igcmg/svn/modipsl/trunk modipsl cd modipsl/util ./model LMDZOR_v6.1.10 cd ../config/LMDZOR_v6 gmake
Install a branch ORCHIDEE with LMDZ
If you want to extract a branch of ORCHIDEE instead of the trunk, first you need to know if the branch is updated or created after the nitrogen cycle was introduced in the trunk, ORCHIDEE/trunk revision 5639. If the branch was developed upon the ORCHIDEE/trunk revision 5639 or later version, then use the configuration LMDZOR_v6.3_work. Otherwise use one of the LMDZOR_v6.1.X configurations. See here an example for extracting and compiling of ORCHIDEE-MICT with the default LMDZ6 version. In the example below you can change ORCHIDEE-MICT into another branch name when you use a different one. .
svn co http://forge.ipsl.jussieu.fr/igcmg/svn/modipsl/trunk modipsl
cd modipsl/util
vi mod.def
Modifiy the line:
#-C- LMDZOR_v6.1.10 tags/ORCHIDEE_2_0/ORCHIDEE 6268 14 ORCHIDEE modeles
Into the line:
#-C- LMDZOR_v6.1.10 branches/ORCHIDEE-MICT/ORCHIDEE HEAD 14 ORCHIDEE modeles
./model LMDZOR_v6.1.10
cd ../config/LMDZOR_v6
gmake
LMDZ at obelix
LMDZ can be used at LSCE/obelix cluster. See here some hints for running LMDZ at obelix https://forge.ipsl.jussieu.fr/igcmg_doc/wiki/Doc/ComputingCenters/LSCE.
