WRF-VPRM Simulations in Complex Topography: Model Configuration and Sample Output Data

This dataset contains model configuration files and sample output data from WRF-VPRM (Weather Research and Forecasting model coupled with Vegetation Photosynthesis and Respiration Model) simulations conducted over complex alpine topography.

Contents:

• WRF-VPRM Model State: Complete model configuration and input files used for the simulations, including:
  • Modified WRF source code with VPRM coupling implementation
  • VPRM parameter files (optimized using FLUXNET observations)
  • WRF namelist configurations for nested domains (54km, 27km, 9km, 3km)
  • Boundary condition files and preprocessing setup
  • Land cover data (CORINE) and VPRM input files generated via pyVPRM and vprm_shapeshifter
• Sample Model Output: One day of WRF-VPRM output data demonstrating the model results (full simulation output is ~5TB)
• Extracted Time Series Data: Site-level and domain-averaged time series extracted from the complete simulation period, enabling reproduction of most figures presented in the associated publication

Model Setup:

The simulations use a coupled WRF-VPRM framework to simulate CO₂ fluxes over the Alps. Key components include:

• Boundary conditions from ERA5 reanalysis data
• CO₂ initial and boundary conditions from CAMS (Copernicus Atmosphere Monitoring Service)
• VPRM parameters optimized using differential evolution against FLUXNET2015 site observations
• MODIS satellite data for vegetation indices (EVI, LSWI)
