Hi, For a course project I used cesm1_0_6 to run the compset B_1850_CN, modifying MONTHLY_LAI in surfdata input to see its effect on the carbon cycle. By plotting the difference I've made sure that the input file is modified. The logs also shows cesm read the modified one. Theoretically, LAI's changing should influence the photosynthesis and then have impact to carbon cycle. However weird things happened. At the first half year, I cannot observe any difference of carbon fluxes or even Total LAI from the output file. I suspect maybe this compset doesn't allow prognotic carbon changes, but it cannot explain the TLAI's remaining. And it seems BGP and CO2A are also activated. Is there anybody who has experience about changing parameter that effects the carbon cycle or who is familiar with the diffences between these compsets? (like, the diffences between B_1850_cn and B_1850-2000_BGC-BPRP) Thanks.
