PCMDI Metrics Package (PMP)

The content of this site is currently being expanded to include examples for all of the PMP summary statistic functionality

The 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. Currently, the comparisons emphasize metrics of large- to global-scale annual cycle and both tropcial and extra-tropical modes of variability. Ongoing work in v1.x development branches include established statistics for ENSO, MJO, regional monsoons, and high frequency characteristics of simulated precipitation.

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

The PMP expects model data to be CF-compliant, otherwise, to successfully use the package may require some input data conditioning.

A suite of demo scripts and interactive Jupyter notebooks are provided with this documentation.


Installation requirements and instructions are available on the Install using Anaconda page

An overview of the summary statistics available via the package are summarized with interactive Jupyter notebooks in the Documentation and Demos page

Some installation support for CMIP participating modeling groups is available: pcmdi-metrics@llnl.gov
