As the Arctic research community transitions to the 2022-2026 Arctic Research Plan, IARPC is reflecting on the achievements of the previous five years. In a three-part webinar series, researchers and community members engaged in Arctic research will  present on highlights of their work in observations, human-applied science, and modeling. Please join us as they share accomplishments of their projects under the 2017-2021 Arctic Research Plan and demonstrate the diverse research associated with IARPC.

This third webinar in the three-part series will focus on accomplishments in modeling. Richard Cullather (NASA) and Wilbert Weijer (LANL) will provide an overview of the IARPC Collaborations Modeling Team's accomplishments over the past five years. Elizabeth Hunke (LANL) will present on the CICE Consortium. Sophie Nowicki (University of Buffalo) will share about ISMIP6.


Richard Cullather is an associate research scientist with the NASA Global Modeling and Assimilation Office at Goddard Space Flight Center, through the cooperative agreement with the Earth System Science Interdisciplinary Center (ESSIC) at the University of Maryland. His research focuses on the implementation and assessment of reanalyses in polar regions and subseasonal-to-seasonal prediction. He is a co-leader of the IARPC Modeling Sub-Team.

Wilbert Weijer is a physical oceanographer by training (PhD 2000, Utrecht University) and a climate scientist by trade. He has been working at Los Alamos National Laboratory since 2006, and is currently leading the HiLAT-RASM project for DOE’s Earth & Environmental Systems Modeling program. He is co-lead of IARPC’s Modeling and Physical Oceanography teams.

Elizabeth Hunke serves as Los Alamos National Laboratory’s Program Manager for Earth and Environmental Systems Sciences Division programs in the Department of Energy Office of Science’s Biological and Environmental Research. She is a Scientist in T-3, the Fluid Dynamics and Solid Mechanics group at LANL, and served as T-3’s Deputy Group Leader, 2015-2020. Elizabeth leads the CICE Consortium, an international group of institutions jointly maintaining and developing the CICE sea ice model in the public domain for the research and operational communities. She also leads Earth System Model Development for DOE’s Integrated Coastal Modeling project. She served as co-chair for the Community Earth System Model (CESM) Polar Climate Working Group for 14 years and now chairs the CESM Advisory Board as well as LANL’s Science Advisory Panel for Laboratory Directed Research and Development in Information Science and Technology. She also served as a U.S. delegate to the International Arctic Science Committee (2011-2019), was a Rothschild Distinguished Visiting Fellow for the Isaac Newton Institute for Mathematical Sciences, University of Cambridge UK in 2017, received LANL’s Fellows Award for Leadership in 2020, and became a LANL Fellow in 2021.

Sophie Nowicki is an Empire Innovation Professor in the Department of Geology and RENEW Faculty at the University at Buffalo. She holds a Ph.D. in theoretical glaciology from University College London (UK). Her research focuses on the Greenland and Antarctic ice sheets, their connections to the Earth’s climate system, and their impact on sea level. Sophie is the co-lead of the Ice Sheet Model Intercomparison Project for CMIP6 (ISMIP6) and is a lead author on the IPCC 6th Assessment Report Chapter on “Ocean, cryosphere, and sea level change.”
