About the function "CO2_biogen()"

[XuanhongZhou]

hi~
I am a beginner of SUEWS. In my work, i only need to use the function "CO2_biogen()" in subroutine co2_module. However, i found some problems when i was looking for the data.

1. Here are some variables that i don't know how to find them: "gfunc, gfunc, temp_c, t2". The document lacks the descriptions of them.
2. The array "SnowFrac", it contains the fraction of snow on different surfaces, i found its description on the website "https://suews.readthedocs.io/en/latest/input_files/Initial_Conditions/Snow_related_parameters.html", however, i found nothing on the configuration part. And here is the same problem with "FAI_id".
   I hope fellow scholars and colleagues can provide me with answers, and I am truly grateful.
