Coupled Model Intercomparison Project Phase 6

This page is intended to provide information on the participation of the Community Earth System Model to the Climate Model Intercomparison Project Phase 6 (CMIP6)

CESM - CMIP6 Projects

Land Use Model Intercomparison Project (LUMIP)

Seeks to address the major science questions related to land-use in the most organized and effective way possible.

As one of the Coupled Model Intercomparison Project Phase 6 (CMIP6) endorsed MIPs, LUMIP will address the following primary questions:

  1. What are the effects of land use and land use change on climate and biogeochemical cycling?
  2. Are there regional land management strategies with promise to help mitigate and/or adapt to climate change?
  3. What are the effects of climate change on land-use and land-use change?
Project Overview

Ocean Model Intercomparison Project (OMIP)

Aims to provide a framework for evaluating, understanding, and improving the ocean, sea-ice, tracer, and biogeochemical components of global climate and earth system models contributing to the Coupled Model Intercomparison Project Phase 6 (CMIP6).

More information coming soon...

Polar Amplification Model Intercomparison Project (PAMIP)

Seeks to improve our understanding of polar amplification through a coordinated set of numerical model experiments.

As one of the Coupled Model Intercomparison Project Phase 6 (CMIP6) endorsed MIPs, PAMIP will address the following primary questions:

  1. What are the relative roles of local sea ice and remote sea surface temperature changes in driving polar amplification?
  2. How does the global climate system respond to changes in Arctic and Antarctic sea ice?
Project Overview Project Publications

Scenario Model Intercomparison Project (ScenarioMIP)

Will provide multi-model climate projections based on alternative scenarios of future emissions and land use changes produced with integrated assessment models. The design consists of eight alternative 21st century scenarios plus one large initial condition ensemble and a set of long-term extensions. Climate model projections will facilitate integrated studies of climate change as well as address targeted scientific questions.

The primary objectives of Scenario-MIP are to:

  1. Facilitate integrated research leading to a better understanding of the physical climate system consequences of future scenarios and their impact on natural and social systems, including adaptation and mitigation considerations.
  2. Provide a basis for addressing targeted science questions about the climate effects of aspects of forcing relevant to scenario-based research.
  3. Provide a basis for various international efforts that target improved methods to quantify projection uncertainties based on multi-model ensembles.

Feedback

CMIP6 is currently asking for feedback on the organization of the various Model Intercomparison Projects (MIPs).

Oversight, Support & Analysis

In order to provide the necessary oversight, support and analysis of the various CESM simulations, it is expected that any CESM participation to a particular MIP will require the identification of an NCAR or external contributor. This person will serve as the point of contact for that MIP and will help in the planning, execution, distribution and analysis of the specific MIP simulations.
