The CH2O-CHOO TRAIN v1.0
ALL ABOARD! The Carbon-H2O Coupled HydrOlOgical model with Terrestrial Runoff And INsolation is a model for long-term climate, weathering, and carbon cycle dynamics. The climate and weathering modules are solved in 1-dimension (zonal mean) and integrated for global mean carbon fluxes.
A preprint describing the model can be found here (doi: 10.31223/X5ND26).

The PATCH Lab
NEW! The PATCH Lab is a web app for archiving and discovering terrestrial stable isotope proxy data to reconstruct past climates and environments. It also includes graphical user interface models for simulating carbon and oxygen isotopes and a list of other research resources.
A preprint describing this effort can be found here (doi: 10.31223/X5PK9W)
Vapor transport model
Kukla et al., 2019 (JGR Atmos.); Kukla et al., 2021 (GPC)
This is a reactive transport model that predicts hydroclimate fluxes and the isotopic composition of rainfall across a 1-dimensional landscape. The model assumes moisture delivery along a dominant storm trajectory (e.g. the westerlies) and is capable of simulating its interactions with topography.
I am happy to assist with any questions you have about running the model. If you use the model, please let me know at tykukla@stanford.edu.
If you use the model for academic work, please cite:

Vapor transport and the isotopic composition of rainfall
Model animation with mountain uplift
Signatures of the same mountain uplift and aridification forcing can be differentially preserved in single-site isotope records, as determined by the landscape's structure. Here, I use the model from Kukla et al., 2019 (JGR Atmospheres) to illustrate these differences across a coastal vs. inland mountain range. I also illustrate that the sensitivity of oxygen isotope records to hydroclimate change depends on the hydroclimate state itself relative to the hydrostat.
