Tests

What will be checked

• Monitoring to compare previous NEMO version with the new one using QCO
• Need to check perfect tracer conservation (suggested by Jérôme)

Comparison with ongoing work on climate projections

3. Ethé has run an experiment with COREII climatological forcing at global 1° resolution (eORCA1). Monitoring is here ​https://vesg.ipsl.upmc.fr/thredds/fileServer/IPSLFS/cetlod/interMonitoring/NEMOvxx_InterMonit/index.html/ Legend (colors of curves):
   • blue is NEMO rev. 3.6
   • read is NEMO rev. 4.0.3
   • yellow is trunk rev 14273 (with key_qco and nn_hhls = 1) as future 4.2 RC

Experience is on irene /gpfswork/rech/gzi/rgzi002/NEMO_r4.2beta/modipsl/config/NEMO_v6/eOR1Si3Pv4x-IA-CORE-02
