 Describes r6614. The concentration of C13 in the leaves can be calculated by setting '''ok_c13''' to y in the run.def. This calculation follows Farquhar's approach and is currently limited to the fractionation in the leaves. Following changes to the recalculation of GPP under plant water stress the calculation of Ci is no longer accurate. This may have broken the functionality to calculate C13. Needs to be tested.
 
+=== Comparing to forest inventory observations ===
+Describes rXXXX. ORCHIDEE calculates the HEIGHT, DIAMETER, BA, and IND for the whole stand including saplings. Forest inventories use a diameter threshold below which trees are not sampled. The HEIGHT, DIAMETER, BA, and IND from a forest inventory cannot simply be compared to the ORCHIDEE simulations. This cut off diameter has been implemented in ORCHIDEE ('''DIA_THRESH_INV''') and enables the model to calculate the simulated HEIGHT, DIAMETER, BA, and IND for the whole stand as well as these variables as if they would be measured in a forest inventory.

 === Configurations ===
 Describes r7671. The model comes with the following well-tested configurations (config/ORCHIDEE_OL). Well-tested means that these configuration have been tested on different servers and some are part of the trusting:

 * OOL_SEC_STO_FG4: ~0.5x0.5 degrees annual CRU-JRA forcing between 1901 and 2010 ([https://forge.ipsl.jussieu.fr/orchidee/wiki/Documentation/Forcings about the forcing]). Start from scratch. 64 PFTs, European forest are defined at the species level with 4 age classes, forests outside of Europe are defined at the MTC level with 1 age class, annual land cover and tree species changes, annual  input deposition, annual CO2 concentrations, annual forest management, and annual litter raking.
 * OOL_SEC_STO_FG5: 1x1 degrees annual IPSL RCP 4.5 forcing between 1911 and 2100. Start from OOL_SEC_STO_FG4. 64 PFTs, no land cover and changes, annual input deposition, annual CO2 concentrations, prescribed species and management changes following annual a stand replacing disturbance, litter raking for 2010.

 * OOL_SEC: 2x2 degrees annual CRU-JRA forcing between 1901 and 2010 ([https://forge.ipsl.jussieu.fr/orchidee/wiki/Documentation/Forcings about the forcing]). Start from scratch. 15 PFTs prescribed by reading in a biomass map. Land cover changes, input deposition, CO2 concentrations, and all other biogeochemical and ecological processes are deactivated. This configuration is under development, waiting for a global LAI map (in case of CN-CAN this has become biomass map) to be tested.
