#201 closed defect (wontfix)

qsintveg can be negative

Reported by: aducharne Owned by: aducharne
Priority: major Milestone: IPSLCM6.v1
Component: Physical processes Version: trunc
Keywords: Cc:


qsintveg(kjpindex,nvm) holds the amount of water that is intercepted on leaves (in kg/m2).

I have a simulation with instances of negative qsintveg, which does not seem appropriate for a water amount.

qsintveg is calculated in hydrol_canop, and updated in hydrol_vegupd.

c'est une conséquence du couplage implicite. On permet une petite interception négative. Mais au prochain pas de temps le vbeta correspondant doit être nul.

dans diffuco il y a un schéma prédicteur correcteur pour essayer de limiter ces cas. Mais il ne peut pas marcher à 100%.
