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

This dataset contains input and sample output data from WRF-VPRM (Weather Research and Forecasting model coupled with the Vegetation Photosynthesis and Respiration Model) simulations conducted over complex alpine topography. It accompanies the manuscript "Sensitivity of CO2 exchange in WRF-VPRM to model resolution and parameter settings over Alpine topography" (Geoscientific Model Development, in review). Contents Input data: - CAMS subset — CO2 initial and boundary conditions from the Copernicus Atmosphere Monitoring Service- VPRM input — CORINE land cover, MODIS-derived vegetation indices (EVI, LSWI), and pre-processed VPRM parameter fields (generated via pyVPRM and vprm_shapeshifter)- FLUXNET2015 — reference site data used for VPRM parameter optimisation and model validation Sample model output: - One day (2012-07-27) of WRF-VPRM hourly output across the nested domains (54 km, 27 km, 9 km, 3 km, 1 km). The full multi-month simulation output is ~5 TB and is not redistributed.

Key components: - Meteorological boundary conditions from ERA5 reanalysis- CO2 initial and boundary conditions from CAMS (Copernicus Atmosphere Monitoring Service)- VPRM parameters optimised using differential evolution against FLUXNET2015 site observations- MODIS satellite data for vegetation indices (EVI, LSWI)- CORINE Land Cover 2018 for land-surface classification Note on prior versions Versions v0.1 and v2 of this record bundled WRF and WPS source code, but those bundles contained upstream code rather than the modified WRF-P and WRF-VPRM-CLC branches actually used in the paper. The modified source is now archived in the three separate records linked above. This v0.2 release retains only the data files.
