Ice Sheet MIP for CMIP6 Meeting
Venue: NASA GSFC, Greenbelt, MD, USA
Dates: 16-18th July, 2014
Meeting Organizers: Sophie Nowicki (GSFC), Tony Payne (University of Bristol), and Eric Larour (JPL).
The sea-level projections made by the glaciological community as part of the IPCC process have often been out of phase with the projections considered by the wider CMIP community. For instance in AR5, the ice2sea and SeaRISE ice sheet projects predominantly worked with AR4 scenarios, while the CMIP5 community used new RCP scenarios. A primary focus of this meeting is therefore to develop a plan that will allow ice sheet and glacier models to be better integrated in the CMIP6 initiative, in order to improve both sea level projections due to changes in the cryosphere and our understanding of the cryosphere in a changing climate. These goals map into the Cryosphere Grand Challenge and the Sea-Level Rise Grand Challenge relevant to CliC and the WCRP. Participation is by invitation only, and will primarily include ice sheet and Earth system model development and analysis leaders, representatives of MIPs that are relevant to the cryosphere and observation data set providers. If you would like to be invited to the meeting or if you would like to join the meeting remotely, the first session will be shared via webex for the images and telecom for the sound, please email Sophie Nowicki.
The meeting goal is to develop an Ice Sheet MIP proposal for participation in the CMIP6 initiative.
Meeting Objectives
- Assess the utility of the current CMIP5 variables over ice sheets, including formatting, documentation, temporal and spatial resolution. Identify which variables are lacking in the current CMIP5 for our purpose and provide recommendation to CMIP6 for additional variables.
- Identify which experiment in the proposed CMIP6 DECK experiment should become the primary focus of the MIP for fully coupled ice sheet – climate models (and how to include feedback for ice models that would be forced “offline”).
- Identify whether additional experiments should be proposed in CMIP6.
- Identify preliminary sensitivity experiments that focus on understanding the source of diversity in modeled responses and feedbacks, towards reducing the uncertainty in sea-level projections. (For examples, how do different beds of initialization methods affect the projections).
- Identify valuable satellite observations and field measurements for model initialization, evaluation and process understanding.
- Draft a MIP template for consideration into endorsement by CMIP6.

Meeting ends |
Breakout sessions will run in parallel and consist of small groups ~6-10 participants. They will normally be split between Greenland, Antarctica and global glaciers, although for some topics other groupings may be necessary. Each breakout will be introduced in plenary by a couple of 10-15 minute talks to give background, highlight key issues and set objectives. Plenary report back sessions will contain a brief summary from each breakout group’s rapporteur followed by synthesis. We will also have additional rooms available, but our main home is H114 in Building 33
