Plant water potential in CLM5.1 using PHS.

I’m working on evaluating how well CLM simulates plant water potential and how it correlates with other simulated variables. From the CLM5 documentation, I understand that plant hydraulic stress (PHS) is included by default, but I want to confirm if this is correct. Also, I’m using CLM5.1 and testing by performing single point simulation. I need to analyze plant water stress at the PFT level. Does CLM5 output this by default, or do I need to modify the output settings? I’ve been searching for a comprehensive list of CLM output variables with their standard names but haven’t found a clear reference. Could someone point me to the right documentation?

The documentation is always a good place to start:

Another way to answer some questions is to start running test simulations and seeing what you get.

Thanks so much for pointing out.
I have another question specifically for running CTSM at NEON sites and hoping to use the most recent NEON tower site data (up to 2025) for both model forcing and evaluation. I’ve noticed that many of the existing workflows and datasets stop around 2021–2022, even though NEON continues to provide updated measurements. I’m wondering if there’s any guidance, tools, or examples available for preparing updated NEON meteorological data—specifically for converting it into the format for use in CTSM.

Thanks!

If you have searched and have not found such tools, then your best bet is to use existing DATM files as the template and convert newer data to match the template.

However, I will tag @wwieder @afoster in case they have a different suggestion.

I think the neon v3 data go through 2023. I'm unclear if they'll have a v4 data release that will include 2024 data.
