Short Summary

This paper introduces the ISIMIP Groundwater Sector, a framework for ensemble modeling to assess global change impacts on groundwater, demonstrating its application by presenting global ensemble mean static water table depth and groundwater recharge changes for 2001-2006.

Objective

• To establish the ISIMIP Groundwater Sector as a standardized framework for ensemble modeling to evaluate global change impacts on groundwater resources.

Study Configuration

• Spatial Scale: Global
• Temporal Scale: 2001-2006

Methodology and Data

• Models used: An ensemble of various groundwater models.
• Data sources: Model outputs derived from already published data, pre-processed and spatially merged using QGIS.

Main Results

• The framework successfully demonstrated the generation of global ensemble mean static water table depth and groundwater recharge change for the period 2001-2006.
• These results represent a preliminary demonstration using available model runs, paving the way for a full ISIMIP ensemble.

Contributions

• Establishes a standardized framework (ISIMIP Groundwater Sector) for multi-model ensemble projections of groundwater changes under global change scenarios.
• Provides a foundational demonstration of how such an ensemble can be constructed and its initial outputs, highlighting the potential for comprehensive global groundwater impact assessments.

Funding

• Not explicitly stated in the provided text.
