Hi all,
I’m running a single-site CLM simulation in SP mode and need to obtain field capacity, wilting point, and porosity for each soil layer to calculate Soil Water Availability (SWA) for that different layer in that specific site. I’ve seen that watsat and watfc are listed among CLM history variables, and I’m wondering if these indeed are the correct variables to use for porosity and field capacity? and if so I can output these by adding them in user_nl_clm. However, I haven’t found any history variables related to wilting point (WP), so I’m unsure how to compute or extract wilting point values per soil layer. Given my limited experience modifying CLM code, I would appreciate expert advice on how best to obtain these parameters. Additionally, would it be better to calculate wilting point externally from soil texture data rather than trying to extract it from the model? Any guidance or suggestions would be very helpful at this point.
Thanks,
Makduma
