605 4829d 01h werner /src/ added the "rid" (i.e. a unique id per resource unit) in various debug outputs.
added the "shell" of a new carbonflow output.
 
595 4843d 04h werner /src/core/ changed behavior of coarse roots: if biomass exceeds value from allometric relation, the excell biomass is pushed to the soil (avoid piling up of coarse root carbon in the soil)
inlined some biomass functions in species.h.
 
588 4857d 02h werner /src/core/ added carbon-bookkeeping in the regeneration layer.  
587 4857d 15h werner /src/ added carbon output.
lots of changes necessary to get this done (especially budgeting of biomass pools)
 
574 4860d 03h werner /src/ * modified outputs to write only rows for valid resource units
* dropped setting "woodDecompRate" (snag.cpp)
* calculate the "stockableArea" of a resource unit based on the stand grid
* use the stockableArea for calculation of LAI
 
564 4870d 19h werner /src/ Improvements of the Management API and functionality.
new functionality:
* killSaplings() -> use a "MapGrid" and remove small trees specifically
* properties defining biomass remove fractions during management

Now the tree list of the management object is cleaned up after a management, i.e. successive managements without reloading the tree list are possible.
 
562 4873d 22h werner /src/ calculate ET0 (reference evapotranspiration) that is used for snag decay 're'. Another version of penman monteith is used for calculation.
See the excel - based "re_decomp.xlsx" for details
 
557 4877d 19h werner /src/ added initialization of snags and some new resource unit variables.
Example: model.initialization node:
<snags>
<swdC>12000</swdC>
<swdCN>120</swdCN>
<swdCount>50</swdCount>
<otherC>4000</otherC>
<otherCN>30</otherCN>
<swdDecompRate>0.05</swdDecompRate>
<woodDecompRate>0.05</woodDecompRate>
<swdHalfLife>30</swdHalfLife>
</snags>
 
553 4878d 23h werner /src/core/ another variant to calculate 're', following Adair et al 2008. Based on monthly sums of precipitation and PET. PET is calculated during the water cycle, monthly precipitation is summed in the climate object itself.  
552 4879d 01h werner /src/ fixed bug when calculating 're' with the day / dayOfMonth confusion. Changed name of the data field to avoid future problems.  
547 4881d 00h werner /src/core/ restructured the topLayerWaterContent setting; it is now RU-specific (and not a global parameter)  
546 4881d 02h werner /src/core/ modified calculation of 're' (decay rate for snags), and added new model setting ('topLayerWaterContent') for that purpose. New variable 'waterDeficit' per day in WaterCycle.  
541 4905d 23h werner /src/ included new setting "model.settings.decayReferencePsi"  
540 4905d 23h werner /src/ removed the storage of rel. water content in water cycle module; changed the way the climate modifier (re) for snag/soil decay is calculated.
Added the coarse wood of died trees to the 5-year decay pattern of branches (and renamed therefore to otherWood).
 
534 4914d 23h werner /src/ large(r) update of the soil model. Now, the 'kyl' and 'kyr' parameters (i.e. decomposition rates for the litter/wood-soil pool) are now species parameters and calculated dynamically from the litter inputs.  
532 4918d 14h werner /src/ force calculation of 're' in Snag even if no snags are present (Soil needs that value later)  
528 4918d 15h werner /src/ more enabling of C/N cycling in iLand. little GUI-feature: click on a RU in resource-unit visualization now properly shows RU-related debug outputs.  
526 4918d 19h werner /src/ embedding the soil model into iLand. renamed the snag decay debug output.  
525 4918d 20h werner /src/ implemented ICBM/2N soil model (class Soil) and some testing code. So far, the results look promising.  
524 4919d 02h werner /src/ some polishing of the snag dynamics and extending the debug output for that.
