The Impact of Supercomputing on Climate Change ResearchNational Center for Atmospheric Research (NCAR)

  • Objective: Utilize HPC to model and predict global climate changes spanning years to centuries.
  • Technical Details:
    • Model: Community Earth System Model (CESM)
    • Supercomputer: “Cheyenne” at NCAR-Wyoming Supercomputing Center
    • Data Storage: GLADE system for petabytes of generated data
    • Visualization Tools: NCAR Command Language (NCL) & ParaView to interpret complex datasets.
  • Application:
    • Initialization: Input real-world observational data into CESM.
    • Simulation: “Cheyenne” runs the model, concurrently simulating Earth systems.
    • Analysis: Results are visualized and patterns in climate variables are interpreted.
  • Key Insights:
    • Supercomputing at NCAR offers detailed, long-range climate forecasts.
    • Predictions show potential shifts in global temperatures, precipitation, and sea levels.
    • Accurate policy-making requires high-quality, bias-free initial data.
  • “Consider the impact of inaccuracies in initial observational data on climate predictions. How can researchers address potential biases?”
