v28 v29 26 26 Finally, the length of the initialization period should be dictated by the slower active component influencing your simulations: 27 27 - If you use ORCHIDEE with STOMATE, use a 20-yr initialization even if you are not interested in LAI, because there is a big feedback between the LAI and the hydrology and energy budgets. And if you're interested in !Sap/Heart/wood C pools, use a 100 to 200 period. 28 - If you're interested in the soil carbon, you need a longer initialization. But it is not required for the moment if you're not interested by the soil carbon, since there is no feedback between the soil carbon pools and the LAI and the hydrology yet.28 - If you're interested in the soil carbon, you need a longer initialization. But it is not required for the moment if you're not interested by the soil carbon, since there is no feedback between the soil carbon pools and the LAI and the hydrology in the default sept. Nevertheless, if OK_SOIL_CARBON_DISCRETIZATION is set to TRUE then some feedbacks are activated and a full spinup is necessary whaterver the variable you are interested in 29 29 30 30 == Standard protocol for Carbon-related variables== … … 42 42 43 43 == The built-in iterative pseudo-analytical spinup configuration == 44 There is a dedicated experiment in directory SPINUP_ANALYTIC_FG1 found in config/ORCHIDEE_OL. 44 There is a dedicated experiment in directory SPINUP_ANALYTIC_FG1 found in config/ORCHIDEE_OL. The analytic spinup is activated through "SPINUP_ANALYTIC=y" in stomate.card. The spinup.driver will then calculate and set spinup_period in run.def using CyclicBegin and CyclicEnd. Note that if this spinup_period is too small it will be adjusted to a higher multiple (close to ten years) automatically by the model due to stability reasons. 45 45 46 46 === Additional knowledge === … … 56 56 57 57 == The old/deprecate SPINUP configuration == 58 The method relies on the SPINUP configuration, which uses the programs forcesoil and orchidee_ol to accelerate the spinup (forcesoil was used to accelerate the convergence of the soil carbon pools only). The directory SPINUP is used to spinup with this method, read more about the method in [wiki:Scripts/SpinUpJobs SPINUP configuration].58 The method relies on the SPINUP configuration, which uses the programs forcesoil and orchidee_ol to accelerate the spinup (forcesoil was used to accelerate the convergence of the soil carbon pools only). The directory SPINUP is used to spinup with this method, read more about the method in SPINUP configuration. This configuration is needed if you activate OK_SOIL_CARBON_DISCRETIZATION.
