Part 2 of the implementation of CO2 effects in STEPWAT2 is an increase in biomass under elevated CO2, which is what this issue covers. This will be implemented by increasing plant-level WUE (represented by bvt (biomass / transpiration) using derived CO2-plant biomass relationships according to CO2 of the RCP-time period combination being simulated.
Proposed functionality:
New CO2 input file that specifies mean CO2 for each RCP-time period combination
New CO2 script that calculates a new denominator for bvt based on either a C3 or C4 species equation between CO2 and biomass response ratios and based on CO2 of the given RCP-time period combination
Changes to Main.R to write new rgroup.in files with the newly derived bvt denominator.
