Last Deglaciation

Description

Group description

This Working Group is coordinating efforts to carry out transient simulations of the last deglaciation (~21-9 ka). It is being implemented in close collaboration with the Last Glacial Maximum PMIP Working Group to maintain consistency across the experiments, and the simulations have been/will be specifically designed to include the full range of PMIP models.

To join the mailing list for the working group, email Ruza: r.ivanovic@leeds.ac.uk.

Historical footnote: group initiated at the PMIP3 2014 Namur meeting.
 

Approach

It is expected that every participant model will run the one Core transient simulation through the full deglaciation (21-9 ka). The only exceptions are the computationally more expensive models for which a multi-millennia transient simulation is infeasible.

In addition to the Core, the working group will coordinate simulations to:

  • Assess uncertainties in boundary conditions and forcings

  • Test specific hypotheses

  • Focus on shorter time periods to involve computationally more expensive models

  • Carry out model sensitivity simulations

  • Begin earlier in the last glacial period (e.g. 26 ka)

We encourage everyone to suggest (and document) further optional simulations.
