7th WGNE Workshop on Systematic Errors in Weather and Earth System Models (SEW 2027)
Dates: 15–19 February 2027
Location: Indian Institute of Tropical Meteorology (IITM), Pune, India
Abstract Submission Deadline: 31 July 2027
The workshop aims to bring together a wide range of experts on simulating the Earth System including atmosphere, ocean, waves, land-surface, atmospheric composition, and associated disciplines to advance the understanding of systematic simulation errors at all timescales. A summary paper will document key findings and identify priority biases in Earth System Models (ESMs).
Of interest are abstract submissions on systematic errors in physics based or machine learning based models, of all components of the Earth System including coupled and individual component models. In broad, submissions can be made under one of these 6 topics. These topics invite contributions that help to increase understanding of the nature and cause of systematic errors in ESMs.
Science Topics include:
- Diagnosing and Attributing Systematic Errors
- Scale Interactions and Resolution Transitions
- Deficiencies in physical parameterisation
- Coupled Earth System Feedbacks
- Impacts on Circulation, Variability, and Predictability
- Uncertainty and Ensembles
2026 American Geophysical Union Annual Meeting (AGU2026)
Dates: 7–11 December 2026
Location: Moscone Center, San Francisco, CA, USA
Abstract Submission Deadline: 5 August 2026
AGU’s annual meeting, the largest gathering of Earth and space scientists, convenes 25,000+ attendees from 100+ countries to share research, connect, collaborate, and inspire one another.
Below you’ll find a non-inclusive list of AGU26 sessions convened by GEWEX community members (indicated by session titles in bold), followed by sessions that are of interest to the GEWEX community
A072 – From Physics to AI: Benchmarking, Bias Diagnosis, and Process Representation in Earth System Models
Conveners: Weiwei Li, Kathryn Newman, Katherine Breen, Mark Carroll, Michael Ek, Sujay Kumar, Lesley Ott, Olya Skulovich, Wenyu Zhou
This session aims to advance community standards for rigorous, interpretable, and application-relevant model evaluation, grounded in physical understanding.
A124 – Years of Precipitation: Coordinating Global Efforts on High-Impact Precipitation Systems through the World Climate Research Programme’s Global Precipitation Experiment
Conveners: Robert Jeffrey Trapp, Juliana Dias, Jin Huang, Annalisa Cherchi
This session marks the launch phase of the YoP, bringing together the community to present new research and coordinated activities. Particularly invited are contributions on the different aspects of precipitation, including novel observations, homogenized or targeted datasets, planned field campaigns, process understanding, model evaluation, extremes, and dataÂmodel integration, including AI/ML. Overall, the session aims to foster international collaboration, advancing precipitation prediction and supporting the development of a globally integrated precipitation research community under the YoP framework.
GC042 Earth System forcing: quantifying the roles and responses of anthropogenic and natural climate drivers
Conveners: Vaishali Naik and Paul James Durack
This session highlights research quantifying uncertainties in the evolution and impacts of these agents using Earth System Models and observations. Contributions are invited across forcing research, including development of historical and future forcing time series, idealized analyses, single- or multi-model frameworks, or observational methods assessing their influence on Earth system dynamics. Of special interested are studies examining responses to next-generation (CMIP7) forcing datasets and comparing them with earlier CMIP phase datasets (CMIP6/CMIP6Plus). Submissions exploring interactions across Earth system components – ocean, atmosphere, cryosphere, land surface and subsurface, and biosphere – and providing evidence of coherent forced responses are encouraged.
GC117 The global water cycle: coupling and exchanges of mass and energy between the ocean, land, cryosphere, and atmosphere
Conveners: Paul James Durack, Jiafu Mao, John T. Reager, Laifang Li, Marybeth Arcodia
This session focuses on water cycle research from an Earth system perspective, emphasizing interactions among the ocean, atmosphere, cryosphere, land surface, and subsurface. Contributions are invited spanning in situ and satellite observations-from past (e.g., Aquarius, TRMM, GRACE), current (e.g., GO-SHIP, Argo, SMAP, SMOS, GRACE-FO, GPM, GCOM-W, SWOT, NISAR), and future (e.g., CIMR, MAGIC) missions-as well as numerical models, data assimilation products, climate projections, and theoretical studies. Especially encourage is work that integrates multiple Earth system components to reveal coupled water cycle variability, long-term change, and underlying mechanisms. Regional and global assessments that identify key observational gaps, emerging priorities, and future needs for monitoring the changing water cycle are also welcome.
107th American Meteorological society Meeting (AMS2027)
Dates: 10–14 January 2027
Location: Denver, CO, USA
Abstract Submission Deadline: 11 August 2026
Below you’ll find a non-inclusive list of AMS2027 conferences that are of interest to the GEWEX community. Sessions convened by GEWEX community members are listed per conference.
- 17th Conference on Transition of Research to Operations [17R2O]
Session 19: Understanding and Evaluating Process Representation in Weather and Climate Models
Conveners: Kathryn M. Newman, NCAR/DTC, Boulder, CO; Co-conveners: Weiwei Li, NCAR/DTC, Boulder, CO; Wenyu Zhou, PNNL, Richland, WA and Michael B. Ek, NCAR, Boulder, CO
This session focuses on understanding and reducing biases across physics-based, AI-based, and hybrid models, with an emphasis on maintaining physical realism. We welcome studies that: 1) identify and diagnose biases in mean state, variability, and key processes, including assessments of physical behavior and consistency in AI-based or hybrid models; 2) use observations to constrain parameterized or learned representations; 3) evaluate both traditional physical parameterizations and ML-based parameterization approaches.
Contributions from testbeds, model-intercomparison efforts, and operational systems are encouraged. The session aims to bring together researchers with expertise in processes who can help advance both physics- and AI-based modeling systems in a physically grounded manner.
