The DYAMOND Model intercomparison(s)#
The DYAMOND initiative (DYnamics of the Atmospheric general circulation Modeled On Non-hydrostatic Domains) provides a framework for the intercomparison of global storm-resolving models—an emerging class of atmospheric circulation models. It is coordinated by the Max Planck Institute for Meteorology (MPI-M) and the German Climate Computing Center (DKRZ) and was supported by the Centre of Excellence in Simulation of Weather and Climate in Europe (ESiWACE).
DYAMOND addresses three main questions:
Where do storm-resolving simulations agree, and where do they provide deeper insights into the climate system?
How sensitive are the simulations to specific model implementations?
What are the performance and analysis bottlenecks associated with global storm-resolving models?
Important
If you use data stored at DKRZ, please acknowledge DKRZ in any resulting publication.
This work used resources of the Deutsches Klimarechenzentrum (DKRZ) granted by its Scientific Steering Committee (WLA) under project bb1153.
Your acknowledgment helps justify the storage and compute resources used for DYAMOND and supports the continued provision of these resources.
In case of questions, please contact the DYAMOND coordination team.
Phases#
To date, the following models have participated in at least one DYAMOND phase:
ARPEGE NH, GEOS, GRIST, ICON, IFS, MPAS, NICAM, SAM, SCREAM, SHiELD, Unified Model (UM).
More information about the models and their experiment runs can be found on the dedicated DYAMOND phase pages.
Analyzing the data#
The two data collections, DYAMOND Summer and DYAMOND Winter, are archived in DKRZ’s tape archive and are accessible via the The DYAMOND Data Library. We encourage you to use our systems for analyzing the data, rather than copying it elsewhere.
To access the DYAMOND data library, you need a DKRZ user account associated with project 1153. To register, visit the DKRZ user management server, use your institutional e-mail address to create an account and ask to be associated with project 1153 (DYAMOND Data Intercomparison). After submitting your request, DKRZ will process it—usually within a few hours. You will then receive a confirmation email with your DKRZ user ID (typically something like b123456). Once your account is confirmed, you can log in to Levante (e.g., ssh -X <user-id>@levante.dkrz.de). For more information, see the DKRZ getting started guide.
If you don’t have other projects at DKRZ, please feel invited to use project 1153 for the DKRZ Jupyterhub and submitting batch scripts. We recommend storing project data under /work/bb1153/<user-id> and using the temporary storage in your scratch folder /scratch/*/<user-id> for processing large datasets. Please clean up your /work directory after completing your analysis. For more information about Levante’s file system, quotas, and backups, see the Levante documentation.
Important
If you are associated with other projects (e.g. MPI-M users), please also register for project 1153 to enable downloading files to the shared cache, but use the other projects for your work, as resources in bb1153 are limited and mainly aimed at providing access to the wider community.
