DevelopmentActivities/ORCHIDEE-DOFOCO
v138 v139 27 27 ORCHIDEE-CN-CAN strengthen the links between sechiba and stomate. As in previous versions, stomate makes use of variables calculated in sechiba but in ORCHIDEE-CAN and ORCHIDEE-CN-CAN, sechiba requires information from stomate to work properly. For the moment set '''stomate_ok_stomate''' to y (_AUTOBLOCKER_). For the future it seems possible to prescribe LAI and assume a canopy structure but this code still needs to be restored and tested. For the time being set '''lai_map''' = n. 28 28 29 30 29 === Allocation === 31 30 ORCHIDEE-CN-CAN uses the allometric allocation as developed in OCN. In ORCHIDEE-CAN the approach was adjusted to work for more than one diameter class. Since it was developed this allocation has been used in ORCHIDEE-CN, ORCHIDEE-CNP and ORCHIDEE-MICT. In those three branches only a single diameter class was used. Except for the way the reserves and labile pools are calculated, the allocation scheme is identical between all aforementioned versions. The model is, however, very sensitive to the way the reserves and labile pools are calculated. The allocation makes use of a labile pool for which the activity is calculated based on the temperature. As such the model addresses the sink/source discussion initiated by Korner. … … 111 110 ORCHIDEE-CN-CAN was developed and tested with CWRR. Set '''hydrol_cwrr''' to y. The Choinel code is still available. The hydrological schemes were not touched during the development of ORCHIDEE-CN-CAN. 112 111 113 === R IVER ROUTING===112 === River routing === 114 113 The river routing code was not touched during the development of ORCHIDEE-CN-CAN. This functionality has not been tested yet for ORCHIDEE-CN-CAN. Unless rivers are your main interest, set '''river_routing''' to n. 115 114 … … 198 197 MENTION conductivities and cavitation 199 198 200 === Dynamic SLA===199 === Specific leaf area === 201 200 Similar to ORCHIDEE-CN, ORCHIDEE-CN-CAN users can choose to use a constant specific leaf area (SLA) or a dynamic (SLA) by setting the flag '''dyn_sla'''. SLA is a fundamental parameter in the allocation scheme and it is well established that SLA is dynamic in nature especially during leaf onset. The current implementation of dynamic SLA is basic and there is room to enhance consistency in the calculations, for example, by recalculation the allocation factors KF and LF as a function of SLA. 202 201 … … 248 247 Recruitment has been developed, tested and validated for tropical forests. There is no reason why it shouldn't work for other forests but that needs to be confirmed. At present recruitment was introduced at the PFT level. It probably makes more sense to link it to the management strategy than to the PFT. This needs to be checked. 249 248 250 === L ITTER RAKING===249 === Litter raking === 251 250 USE_LITTER_RAKING=n 252 251 253 252 254 === C OMMING SOON===255 Land cover change has been coded for age classes in ORCHIDEE-CAN. This code still needs to be merged into ORCHIDEE-CN-CAN. For the moment set '''land_cover_change''' = n and '''veget_update''' = 0Y.256 257 Following a disturbance, tree species changes and forest management change can be prescribed or read from a map in ORCHIDEE-CAN. This code still needs to be merged into ORCHIDEE-CN-CAN. For the moment set '''lchange_species''' = n, '''read_species_change_map''' = n, and '''read_desired_fm_map''' = n253 === Comming soon === 254 1 - Land cover change has been coded for age classes in ORCHIDEE-CAN. This code still needs to be merged into ORCHIDEE-CN-CAN. For the moment set '''land_cover_change''' = n and '''veget_update''' = 0Y. 255 256 2 - Following a disturbance, tree species changes and forest management change can be prescribed or read from a map in ORCHIDEE-CAN.
