Hello
I’m working on reproducing the Plumber 2 simulations with some changes on the parameter values, but I’m uncertain how the original simulations were spun up. The Plumber 2 webpage (ModelEvaluation.org) mentions that these runs were spun up with the forcing data, but I would greatly appreciate any additional details you could provide on the specific spin-up procedure.
Since the Plumber 2 simulations used prescribed vegetation, my understanding is that accelerated decomposition (ad) and post-ad spin-ups should be bypassed, and instead, the simulations should use the prescribed LAI. I’m relatively new to running these simulations, and I’ve been following this tutorial (CTSM-Tutorial/notebooks/Day2a_GenericSinglePoint.ipynb at Mini-Tutorial-2022 · NCAR/CTSM-Tutorial), which only demonstrates a spin-up with ad and post-ad.
Could you confirm whether skipping the ad/post-ad steps is correct for reproducing the Plumber 2 setup? Any guidance or documentation you have would be extremely helpful.
Warm regards,

What version of the code are you using?
Have you made any changes to files in the source tree?
- No.
Describe every step you took leading up to the problem:
- Read the documentation
- Test the ad, post-ad, and transient approach.
