PCMDI Metrics Package (PMP)

The PCMDI Metrics Package (PMP) is used to provide "quick-look" objective comparisons of Earth System Models (ESMs) with one another and available observations. Results are produced in the context of all model simulations contributed to CMIP6 and earlier CMIP phases. Among other purposes, this enables modeling groups to evaluate changes during the development cycle in the context of the structural error distribution of the multi-model ensemble. Currently, the comparisons emphasize metrics of large- to global-scale annual cycle, tropical and extra-tropical modes of variability, ENSO, MJO, regional monsoons, high frequency characteristics of simulated precipitation, and cloud feedback.

PCMDI uses the PMP to produce quick-look simulation summaries across generations of CMIP.

The metrics package consists of the following parts:

The package expects model data to be CF-compliant. To successfully use the package some input data "conditioning" may be required. We provide several demo scripts within the package.

Documentation

Getting Started

  • Installation requirements and instructions are available on the Install page

  • Users will need to contact the PMP developers ([email protected]) to obtain supporting datasets and get started using the package.

  • An overview for using the package and template scripts are detailed on the Using-the-package page
