v155 v156 22 22 == How can I contribute to this version? == 23 23 Given the large number of code changes, there is no guarantee that the current version of AR6v2 will run flawless for all set-ups and possible combinations of flags currently being used by ORCHIDEE users and developers. (1) All users and developers are invited to install AR6v2 and set-up their favorite simulation. Use one of the attached run.def as a starting point for your favorite set-up. Report on the outcome of your tests during the ORCHIDEE meetings. (2) All developers are invited to contribute bug fixes, and code for improved functionality to AR6v2. (3) adjust the interface such that AR6v2 can be coupled to the latest version of LMDz and can be used for regional simulations with WRF. 24 25 24 26 25 == How do I run this version? == … … 234 233 The following PFT dependent parameters are needed for the calculations accounting for plant hydraulic architecture; minimal leaf water potential '''PHI_LEAF_xx''', sapwood leaf water potential that causes 50 % loss of xylem '''PHI_50_xx''', additive tuning parameter to account for soil-root interactions '''PHI_SOIL_TUNE_xx''', maximum sapwood conductivity '''K_SAP_xx''', root conductivity '''K_ROOT_xx''', leaf conductivity '''K_LEAF_xx'''. 235 234 235 EXPLAIN: SOIL_TO_ROOT. This is the new default. The other one is as a backup for DESIRE. 236 236 237 === Recruitment === 237 238 When stands grow old the tree density decreases and under certain conditions the LAI can no longer cover the ground area. When this happens productivity will start to decrease. In nature the decrease in LAI comes with an increase in the amount of light reaching the forest floor which enables seedlings to grow and to restore the LAI. This process is known as recruitment. Note that in managed forest and forest with a lot of stand replacing disturbances (for example, fire) the forest may never reach the stage where the canopy sufficiently opens up to enable recruitment. … … 243 244 === River routing === 244 245 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. 246 247 === Soil maps === 245 248 246 249 === Single layer vs multi layer energy budget === … … 327 330 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. 328 331 332 === Wind throw === 333 EXPLAIN
