Global Physically-Constrained Deep Learning Water Cycle Model with Vegetation: Model Simulations

Welcome to our repository, which features simulations from the Hybrid Hydrological Model with Vegetation (H2MV). This collection includes 11 NetCDF files, representing temporal model simulations on a monthly scale and the static output of maximum soil moisture capacity (also known as plant rooting water storage) derived from a 10-fold cross-validation (CV) setup:

Temporal Simulations: The files named "fold1.nc" through "fold10.nc" contain the temporal model simulations, aggregated to a monthly scale, from 10 fold cross-validation (CV) setup.

Static Output: The "sm_max.nc" file presents the H2MV's estimation of the maximum soil moisture capacity

Contents of the Temporal Simulation Files

Each of the "fold" files ("fold1.nc" to "fold10.nc") contains the following variables:

Snow Dynamics

snow_acc: Snow accumulation (mm/day)

snow_melt: Snow melt (mm/day)

swe: Snow water equivalent (mm)

Evapotranspiration and its components

Ei: Interception evaporation (mm/day)

Es: Soil evaporation (mm/day)

T: Transpiration (mm/day)

ET: Evapotranspiration (mm/day)

Recharge

r_soil: Soil recharge (mm/day)

r_gw: Groundwater recharge (mm/day)

Runoff

runoff_surface: Surface runoff (mm/day)

baseflow: Baseflow (mm/day)

runoff_total: Total runoff (mm/day)

Water Storages 

GW: Groundwater (mm)

SM: Soil moisture (mm)

tws: Terrestrial water storage (mm)

tws_anomaly: Anomalies of terrestrial water storage (mm)

Vegetation

fapar: Fraction of absorbed photosynthetically active radiation (-)

Contents of the Static Output File

The "sm_max.nc" file contains 10 variables corresponding to the 10 folds of CV, with each variable (e.g., "fold1") referring to the respective fold.

Additional Information

It's important to note that the original model simulations were conducted with a daily temporal resolution, but the data shared here have been aggregated to a monthly scale. We are open to sharing the original daily simulations and additional variables not included in this repository upon request. Please feel free to reach out to us for more information or data requests.
