639 4800d 15h werner / move current content to the "trunk"  
536 4955d 16h werner /src/core/ update the calculation of belowground allocation. Due to a mishap an error was in there (a difference in implementation and concept). In short, the fraction of utilizable and global radiaton was not in the formula.
german info:
Eq. S13: ok, gut das wir da noch einmal gecheckt haben. Sollte so sein wie urspruenglich im Supplement (und auch im Wiki), also mit dem uAPAR/APAR ratio und fN. In fact, wenn die Pflanze Trockenstress hat, sollte mehr in die Wurzeln gehen, das ist die Logik dahinter. Ich nehm mal an das das einiges aendert, wir sollten es aber bereinigen. Kannst es mir ev. im project file als switch anlegen? Dann kann ich den Effekt besser testen. Thx und sorry fuer ev. Unklarheiten in der Kommunikation.

--> ok. da gibt es ein neues setting: "usePARFractionBelowGroundAllocation" (in "model.settings") . Wenn true (das ist auch default), dann wird das so gerechnet wie im paper, mit false ist es die "alte" und falsche variante. Und wahrscheinlich hab ich das versemmelt und irgendwie übersehen - es tut eher mir leid, wenn du jetzt deswegen noch recht viel arbeit hast... sorry.
 
513 4981d 19h werner /src/core/ fixed a nasty bug: if one tree species succeeded to establish on a formerly empty RU, the saplings of other species were killed (well, not directly, but the environment was not recalculated leading to a f_env value of 0).  
485 5010d 19h werner /src/ multithreading-bug during calculation of yearly radiation sum  
483 5010d 21h werner /src/core/ recruitment: recruit the number of individuals provided by the Reineke equation.
(correct spelling error: reinecke -> reineke)
 
480 5011d 01h werner /src/ debug message for fenvyr>1,
open file convenience
 
467 5017d 00h werner /src/core/ added species-parameter "sapReferenceFactor" (for calculation of f_env,yr for sapling growth).  
440 5120d 20h werner /src/core/ climate: added a pre-calculated value for the 10.5hrs day
including establishment calculation in the normal execution path.
 
437 5121d 19h werner /src/core/ corrected f_env,yr calculation  
436 5121d 20h werner /src/ climate: added totalRadiation() function
production3pg.cpp: added the calculation of the f_env,yr (total environmental performance of a species)
 
369 5193d 23h werner /src/ * multithreading for 3pg production (crashes)
* do 3PG calculation only if this RU has some leafarea of a species (added clear() functions)
* added GUI-accessible speciesindex-variable for trees
 
327 5324d 17h werner /src/ changed mode of radiation calculation  
300 5341d 00h werner /src/ changed CO2 response from yearly to monthly resolution  
280 5369d 12h werner /src/ Creation of the "Environment" class (loading of the "world" into iLand).
- added setter-functions to XmlHelper
- added auxiliary functions to CSVFile
- smaller changes to a bunch of other files.
 
273 5373d 03h werner /src/ changed the way of aggregating the daily environmental responses. Now, the minimum of the response values for vpd, temperature and soil water is calculated daily and aggregated for each month. the utilizable radiation then is simply rad*avg_min_response. Brief tests showed, that the difference to the "old" multiplicative approach is not very large.  
251 5376d 10h werner /src/ Light-Redistribution: Changed again (12.10.2009). LRI of trees are now modified with a modifier based on stockedarea*beerLambert-fraction (pPar). The modified LRI is then used to calculate a light response. The light response * leafarea eventually acts as the share of GPP assigned to a particular tree.  
230 5382d 04h werner /src/ 3PG work out  
228 5383d 08h werner /src/ created output for production details.  
227 5383d 09h werner /src/core/ 3pg production, documentation polish  
226 5383d 09h werner /src/core/ working on 3pg, the species specific responses and linking it all together.
