JGCRI Models, Tools, and Data

This page provides a list of links to JGCRI models, tools, and archived datasets. For more general information on JGCRI research please see the JGCRI Research and About JGCRI pages.

Models

• Global Change Analysis Model (GCAM) – JGCRI flagship global integrated model
• Global Change Analysis Model -USA (GCAM-USA) – GCAM with USA state-level breakout
• Hector- Reduced-Form Climate Model
• Hector UI – Web interface for the Hector model 
• Superwell- Physics-based hydro-economic model for groundwater cost and supply
• Xanthos- Global Hydrologic Modeling Framework 
• GCAM is also a component of the Energy Exascale Earth System Model (E3SM)

Note that many of these tools were developed through the Global Change Intersectoral Modeling System [GCIMS link: https://gcims.pnnl.gov/modeling] project which links GCAM and a suite of models and tools. Additional information at https://jgcri.github.io/gcims_integration/.

What we do

• Develop next-generation human-Earth system models 
• Develop data products for integrated research, modeling, analysis and decisions
• Improve fundamental understanding of human and Earth system processes, dynamics, and interactions
• Advance the science of impacts, adaptation, and vulnerability to inform decisions
• Analyze technology, policy, and institutional options in energy, water, and land systems
