    1010- Revision 3710 includes an updated stomate scheme. This revision features an optional hack which takes all carbon required for autotrophic respiration from the atmosphere. It was found that this allows most PFTs to grow (mostly) normally. The relevant changes are contained in stomate_growth_fun_all.f90.   The model runs for 102 years with no crashes.  
    11 - [NOT solved] Some PFTs still have abnormalities in their long-term growth and decay patterns; PFT 19 (Broadleaved Summergreen Temperate age class 02) shows a sudden bump in growth from age class 01 that continues until the trees graduate to the next age class. PFT 28 (Broadleaved Summergreen Boreal age class 03) shows jumps in mean tree diameter that coincide with sudden drops in individual tree density. This behavior is unexpected for unmanaged tree stands. See attached pdfs for data. 
     11- [NOT solved] History variables BM_ALLOC_RES_c and BM_ALLOC_RES_n are written with invalid data. C and N in the reserve pools are contained in the variable RESERVE_M_c and RESERVE_M_n. 
     12- [NOT solved] Some PFTs still have abnormalities in their long-term growth and decay patterns; PFT 19 (Broadleaved Summergreen Temperate age class 02) shows a sudden jump in growth from age class 01 that plateaus until the trees graduate to the next age class. After 100 simulation years, PFTs 18 and 22 (Broadleaved Summergreen Temperate age class 01, Needleleaf Evergreen Boreal age class 01) both contain a sharp spike in atm_to_bm-N. This spike should coincide with a sudden increase in indivdual tree density, but this does not seem to be the case. PFT 28 (Broadleaved Summergreen Boreal age class 03) shows jumps in mean tree diameter that coincide with sudden drops in individual tree density. This behavior is unexpected for unmanaged tree stands. See attached pdfs for data. 
    1213- [NOT solved] Alex will continue to work with respiration to try to develop a working version without using this hack.
