GLOBGM_CMIP6: A Global Hyper-Resolution Groundwater Dataset for Assessing Historical and Future Groundwater Dynamics Under Climate and Socioeconomic Change - [quality_assurance]
This data package forms part of the GLOBGM_CMIP6 dataset which was simulated using GLOBGM, a global groundwater model. GLOBGM was used to estimate global water table depth and groundwater heads at a spatial resolution of 30 arc-seconds (~1 km). The model was forced with outputs from the PCR-GLOBWB model, obtained through the HYPFLOWSCI6 project. We provide long-term average, annual, and monthly estimates of water table depth and groundwater heads at the global scale for a historical reference simulation following the ISIMIP3a protocol. This protocol is designed for model evaluation and impact attribution. Additionally, we provide outputs following the ISIMIP3b protocol, which focuses on impact attribution and climate change impact assessment. These outputs cover the historical baseline period (1960–2014) and future projections (2015–2100) under three SSP-RCP scenarios: SSP1-2.6, SSP3-7.0, and SSP5-8.5. The data include simulations from five Global Climate Models (GCMs): GFDL-ESM4, IPSL-CM6A-LR, MPI-ESM1-2-HR, MRI-ESM2-0, and UKESM1-0-LL. The date here pertains to quality assurance.
