Fourth Workshop on Coupling Technologies for Earth System Models (CW2017)

last modified Dec 08, 2020 01:49 PM

The Fourth Workshop on Coupling Technologies for Earth System Models (CW2017) was held on the 20th-22nd of March, 2017 at the Princeton Center for Theoretical Science on the campus of Princeton University, USA.

The workshop aims to bring together leading researchers and practitioners in the field of coupling infrastructure for Earth System models. This workshop is the fourth in a series, the first being held at CERFACS in December 2010, the second at NCAR in February 2013, and the third in Manchester in April 2015.

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

  • Development and use of coupling technologies for Earth System Models
  • Performance considerations of couplers
  • New developments in existing coupling infrastructure
  • Couplers, metadata and workflows
  • Coupling frameworks in the broader geosciences
  • Science of coupling (interpolation methods, convergence, stability)


This workshop is sponsored by IS-ENES2 and the Princeton University Cooperative Institute for Climate Science.
