  • open source software (python)
  • community tool for diagnosis of model performance
  • works across different climate models (facilitate model

intercomparison)

  • main focus on climate variabilities (high-frequency output)
  • modular coding with high flexibility
  • produces an html file for easy web browsing

Summary

AMS Annual Meeting 2018/1/9 14

  • Goal of this project is to create a user-friendly diagnostic

package for diagnosis for climate variabilities of model simulations, using open source software.

  • A preliminary version of the diagnostic package has been

released to the task force in Nov 2017. Additional diagnostics are being implemented.

  • We expect the diagnostic package to be released to the

public later this year.
