Changeset 6393 for branches/ORCHIDEE_2_2/ORCHIDEE/orchidee.default

Timestamp:

Message:

As done in ORCHIDEE_2_0:
Added new option for downregulation parametrization. Set DOWNREGULATION_CO2_NEW=y in run.def to activate. This option will be availble for configurations IPSLCM66.1.11 and later.

IF both DOWNREGULATION_CO2 and DOWNREGULATION_CO2_NEW are true, then DOWNREGULATION_CO2 will be set to false.

See ticket #641
