  • Resolution set to fixed
  • Status changed from new to closed

Phenological growth seemed to have worked correctly but for this pixel and PFT some of the three circ_class got a negative growth which made b_inc_tot increase. Negative growth was because both roots of the quadratic equation were negative. If both roots are negative, we don't allocate and simply leave the carbon in the labile pool. We will try again with more carbon the next day. This change has been committed in r6574.
