+===== Collaboration =====
+  * The PMIP4-CMIP6 **lig127k** simulation is being coordinated with [[http://www.climate-cryosphere.org/activities/targeted/ismip6|ISMIP6]]. The output from the lig127k simulation will be used by ISMIP6 to force standalone ice sheet experiments (//lastInterglacialforcedism//). This will increase our understanding of the sensitivity of the ice sheets, complementing the suite of standalone ISMIP6 ice sheet experiments.
+  * The PMIP4-CMIP6 **midHolocene** and **lig127k** simulations are also expected to be relevant to analyses in [[http://www.climate-cryosphere.org/activities/groups/seaicemodeling/simip|SIMIP]]’s assessment of the role of sea-ice changes in climate changes and [[https://cmip.ucar.edu/aer-chem-mip|AerChemMIP]]’s assessment of the role of dust
