PFT-specific LAI

Dear Sir/Madam,We are using CLM to examine the effects of land cover and vegetation changes (e.g., being harmed by ozone, T, etc.) would affect atmospheric chemistry. One of the issues, surprisingly, that we are encountering a lot is the inability to output dynamically changing PFT-specific LAI because only the total TLAI and ELAI are in the master variable list. It's also not possible to backtrack PFT-specific LAI from PFT fraction and total LAI alone. Has anyone worked around this issue and had codes/suggestions that can help us diagnose PFT-specific LAI in BGC or CN mode?Thanks a lot!

You can get "1d" output of TLAI (pft-specific) and other history fields by setting hist_dov2xy = .false.
See:Outputting history files as a vector in order to analyze the plant function types within gridcells
