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.

Experiment design
Discussions on the experiment design(s) and presentation of the boundary condition data are available through the following links:
-
Alternative challenge simulations:
-
full transient simulations [not live yet]
-
shorter challenges [not live yet]
-
When the experiment designs are finalised, the boundary condition data will also be downloadable from these pages.
