WCRP Agenda


Ultra-high-resolution climate models at km-scale (‘K-scale’) are within our grasp and provide the potential for major advances in both climate science and its applications for societal needs. K-scale models are being developed at both regional and global scale across the world with the aim to develop fully integrated coupled modelling systems. Perhaps naturally, much of the effort so far has been divided by the spheres of the climate system, with significant activities in atmospheric, ocean, land, and ice modelling.

The main purpose of this workshop is to bring together modellers across all spheres to share progress and discuss the major challenges and opportunities in building kilometre-scale global and regional modelling systems. A particular goal of the workshop is to identify opportunities for joint experimentation and model analysis across regions and spheres.

To facilitate the exchange of ideas the workshop will include both invited and contributed presentations. Those will be complemented by a series of breakout group discussions around a common set of questions aimed at generating and sharing ideas on the practical pathways for future collaboration and research in coupled K-scale modelling.

We are looking forward to seeing you in Boulder.
