6th Workshop on Coupling Technologies for Earth System Models (CW2023)

CERFACS and Argonne National Laboratory organise the “6th Workshop on Coupling Technologies for Earth System Models (CW2023)” on January 18-20, 2023 at the “Centre International de Conférences” on Météo-France campus in Toulouse, France.

The workshop aims to bring together leading researchers and practitioners in the field of coupling infrastructure for Earth System Models. This workshop is the sixth in the series, started in 2010 in Toulouse and followed by Boulder USA (2013), Manchester UK (2015), Princeton USA (2017) and virtual (2020).

Topics relevant to the workshop include, but are not limited to:

  • Coupling technology latest developments
  • Use of Coupling Technologies in ESMs or other climate and weather-related coupled systems: successes and failures, original or ground-breaking applications
  • Computational performance of Couplers and Coupled Systems
  • Coupling at exascale on heterogeneous systems.
  • Science of Coupling and Coupling Strategies
  • Integration of coupling technologies into workflows
  • Interaction of data assimilation and coupling technologies
  • Software development processes for complex coupled systems: Approaches for testing of complex coupled models, how code chages are made, build system, configuration system.
All details can be found on the CW2023 web page.


ISAF project : To accelerate the transition to SAFs, SAFRAN and CERFACS have together obtained an allocation of 44 million CPU hours on the LUMI-C super-computer as part of the EuroHPC Regular Access call in November 2022.

The objective of the ISAF project is to study the impact of SAFs (Sustainable Aviation Fuels) on engine operation and pollutant emissions, using high-fidelity Large Eddy Simulations (LES). The methodology developed at CERFACS combines Analytically Reduced Chemistry (ARC) with a multi-component evaporation model to capture the effect of fuel. The target configurations range from academic burners (CRSB at CORIA, SSB at DLR Stuttgart), to isolated industrial injection systems (MICADO at ONERA, HERON at CORIA) and complete annular combustor configurations (BEARCAT at SAFRAN, NTNU test bench).Read more

The recently published paper in Physics of Plasma: "3D particle-in-cell study of the electron drift instability in a Hall Thruster using unstructured grids," by W. Villafana, B. Cuenot, and O. Vermorel ( attracted the attention of Scilight (), whose goal is to present the most interesting research in the physical sciences published in AIP journals."Read more
