This workshop brought together a representative large fraction of active sea-ice modelers. This allowed for a very constructive discussion that will in particular inform the CMIP6 modeling activities related to sea ice. This workshop was key for defining sea-ice variables for CMIP6, which will allow for a more in-depth analysis of sea ice from any CMIP6 experiment. The workshop participants also signaled that they would be very interested in continuing these discussions and in particular in allowing for a broader exchange of sea-ice model development ideas and issues. These will be, among others, the topic of a follow-up workshop in 2015.
