How to run a simple test with ORCHIDEE offline with libIGCM

Author: J. Ghattas Last revision: 2023/11/30, J. Ghattas

We’ll now make a first test for 3 years using the experiment set up in FG_CRUJRA_HIST. This experiment is a global historical set up using the full ORCHIDEE model in offline mode. It uses the driver "orchideedriver" also called ”the new driver”. You’ll launch using the default set up.

Prepare the experiment folder and create the job

Do as follow:

cd modipsl/config/ORCHIDEE_OL
cp -r FG_CRUJRA_HIST MyFirstTest
cd MyFirstTest

The file config.card contains the main settings for the experiment. Change this file and create the job. You can use vi, emacs or an editor of your choice. Do as follow:

vi config.card  => Change to have the following:
  JobName=MyFirstTest
  DateEnd=1903-12-31
  PeriodLenght=1Y

By default, monthly mean output are set. If you want to change the frequency or add high frequency output, read comments and modify in COMP/sechiba.card and COMP/stomate.card.

Now create the main job (you'll have to answer questions which depend on the machine):
