Tatiana Ilyina becoming Co-Chair of Working Group Coupled Modelling in the World Climate Research Program (WCRP)

Dr. Tatiana Ilyina, group leader of the “Ocean biogeochemistry” group in the department “The Ocean in the Earth System”, became co-chair of Working Group Coupled Modelling (WGCM) in the World Climate Research Program (WCRP) starting in January 2022. She will thereby replace Catherine Senior, MetOffice, UK, after her six years term as co-chair, who will stay until the end of 2022 for a hand-over period. The MPI-M congratulates Tatiana Ilyina to this nomination.

“Tatiana Ilyina’s research interests in carbon cycle feedbacks and predictability and variability will fit very well helping WGCM thrive under ESMO (Earth System Modelling and Observations) and the new WCRP structures”, say Cath Senior and Gregory Flato, Canadian Centre for Climate Modelling and Analysis, University of Victoria, Canada, also Co-Chair.


In the next years WGCM will address a number of exciting challenges, for instance: How to strike the right balance between cutting-edge science and inclusiveness in coupled modeling? How to lessen the gap between ultra-high resolution and complexity? Tatiana Ilyina will also lead the writing of the ESMO’s Science Plan related to the carbon budget part.


“WGCM is a delivering, dynamic, and a scientifically engaging element of WCRP with a great influence in climate science. I am very honored and excited about my new role,” says Tatiana Ilyina.



The overall mission of the WCRP Working Group on Coupled Modeling (WGCM) is to foster the development and review of coupled climate models and Earth System models. This includes the organization of model intercomparison projects aimed at understanding natural climate variability and predictability on decadal to centennial time scales, and predicting the response of the climate system to changes in natural and anthropogenic forcing.

WGCM, in collaboration with many groups and partners within WCRP and beyond, endorses and oversees the Coupled Model Intercomparison Project (CMIP), aiming to understand past, present and future climate changes arising from natural, unforced variability or in response to changes in radiative forcing in a multi-model context. CMIP is now in its sixth phase, and views towards seventh’s phase are currently being consolidated.

The Earth System Modelling and Observations (ESMO) Core Project is one of six enduring research communities, called ‘core projects’ of the WCRP, approved by the Joint Scientific Committee (JSC) in November 2020. It is formed to coordinate all modelling, data and observations activities across WCRP and the key partners. ESMO will bring together existing modelling and data elements of the WCRP structure. WGCM will play a key role in ESMO.

ESMO takes a seamless and value-chain model-data-observation approach across Earth system components, fundamental and applied disciplines, time and spatial scales and infrastructures. It aims to optimize model development, establish new prediction systems, innovate observing systems, improve climate data ecosystems and connectivity, advance data assimilation and digital-twin frameworks. This framework will enable the formulation of WCRP modelling and observational requirements to observe, understand and predict the climate system.
