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. |

climate: added totalRadiation() function

* 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 |

changes in the watercycle.
see http://iland.boku.ac.at/tiki-view_tracker_item.php?itemId=30
the calculation of the effect on the canopy conductance is changed. Now, the combined effects of soil water and vpd response together modify the canopy conductance. In order to do this some structural changes have been necessary. Note: now the response values for vpd and soil water are calculated two times. |

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. |

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. |
