The Sea Ice Model Intercomparison Project requests feedback from the
Arctic community on Phase 6 of the Coupled Model Intercomparison Project
(CMIP6). The draft is available in PDF and Excel formats at:
http://www.climate-cryosphere.org/activities/targeted/simip. Input must
be submitted by Tuesday, 31 March 2015.

CMIP6 is intended to harmonize and improve the way in which sea-ice
related variables are saved in CMIP6 and other large-scale modeling
activities. The variables allow researchers to analyze the three budgets
that govern the evolution of sea ice and its impact on the Earth's
climate system, namely conservation of heat, the momentum balance and
tracer conservation. In addition, variables are included that allow for
the high frequency analysis of the sea-ice state itself.

The proposed variable list updates and unifies some of the definitions
included in CMIP5 to more closely resemble the actual physical quantity
(e.g., sea ice thickness). In addition, it includes new variables that
are needed for an in-depth understanding of sea-ice evolution in CMIP6
simulations. The list was initiated at the 2014 Large-Scale Sea Ice
Modeling workshop organized by the CliC Sea Ice and Climate Modeling
forum and then later refined by the co-Chairs of SIMIP and the SIMIP SSG.
