Last Deglaciation Core Experiment Design
Go back to the main working group page.
Please note this page is a work in progress and is not ready for discussion yet.
Proposal
Following wide consultation over the past year, this is our first-draft proposal for the last deglaciation core simulation. Please use the 'Discussion' section below to comment on the proposal and make suggestions for ammendments.
21-9 ka
All core simulations must span this time-period. Use:
26-21 ka
For those who wish to begin their simulation from before the PMIP LGM, use:
