Polar Climate and Ocean Model Working Group Meeting 2026

February 5-6, 2026
8:00am-5:00pm
Hybrid meeting

The meeting will be hybrid, with in person meetings at the NSF NCAR Mesa Lab, Boulder, CO.

Please use this link to submit a talk or register for the meeting.

Ocean Model Working Group - OMWG

The goals of the CESM OMWG are to support the broad scientific objectives of CESM by developing and maintaining a state-of-the-science ocean component model and to serve as a nexus for community-led discovery-based and solution-driven research in oceanographic and Earth system sciences using CESM. The Ocean Model Working Group is currently transitioning from the Parallel Ocean Program (POP2) to the Modular Ocean Model version 6 (MOM6) as the dynamical ocean component model. The latter will provide additional flexibility, usability, and accuracy, enabling CESM to address Earth system research questions across a wider range of scales and interface with new components such as dynamic ice sheets and regional and coastal models.

Polar Climate Working Group - PCWG

The PCWG is a consortium of scientists who are interested in modeling and understanding the climate in the Arctic and the Antarctic, and how polar climate processes interact with and influence climate at lower latitudes. Our members come from universities and laboratories, and our interests span all elements of polar climate, from the ocean depths to the top of the atmosphere. In addition to conducting scientific modeling experiments, we are charged with developing and maintaining the state-of-the-art sea ice model component (CICE) used in CESM.

We invite you to submit abstracts for the 2026 CESM OMWG and/or PCWG winter working group meetings, to be held February 5 and 6, 2026, in Boulder, Colorado, and online. This year, we will have a joint session between OMWG and PCWG on Ice-Ocean-Wave interactions, and we particularly invite abstracts related to that joint session. We will also have individual OMWG and PCWG sessions and solicit presentations focused on the development and use of ocean or sea ice models in CESM, as well as studies using other models that have science of interest to current MOM6/CESM or CICE6/CESM developers and users.

The deadline to submit a talk is January 7, 2026
The deadline to register to attend in person is: January 23, 2026
Registration for remote participation will remain open throughout the meeting.

In-person participation registration is 80 USD for the full meeting or 40 USD for a single day.
