The FATES cold hardening scheme had been Merge to master?

Hello
Whether the FATES cold hardening scheme has already been merged into the master branch of the repository?
Inclusion of a cold hardening scheme to represent frost tolerance isessential to model realistic plant hydraulics in the Arctic–borealzone in CLM5.0-FATES-Hydro.pdf

Hi @LianGong98. No this has not been merged to FATES main. The relevant PR is here: #836. Note that this PR is behind the current main tags. Are you interested in utilizing the features associated with this code?

Hi @glemieux . Thank you for your reply. My single-point simulation is located on the northeastern edge of the Tibetan Plateau, where the minimum temperature during the winter is -25°C.

When using the default hydraulic parameters, the simulated leaf water potential reaches -70 MPa during the winter, which is clearly unreasonable. I'm unsure whether the issue lies with the hydraulic parameters or if I need to consider incorporating the cold hardening scheme.

I would greatly appreciate any guidance on adjusting the parameters or using this scheme.
