DYAMOND stands for DYnamics of the Atmospheric general circulation Modeled On Non-hydrostatic Domains.

R2B10 (2.5km resolution) ICON NWP simulation after 26h of execution. Start date is the 11 Aug 2016.

2.5km global atmospheric simulation using the ICON model.



Project DYAMOND describes a framework for the intercomparison of an emerging class of atmospheric circulation models that, through their resolution of the major modes of atmospheric heat transport, endeavor to represent the most important scales of the full three-dimensional fluid dynamics of the atmospheric circulation. Phase 0 of DYAMOND will compare at least two models (ICON and NICAM). The project is, however open to all and several groups from the US have indicated their interest in participating. Simulations will be performed for a forty day period with the goal of: (i) identifying similarities and differences that emerge at storm resolving scales (1 km to 5 km) as compared to traditional (hydrostatic-scale) representations of the atmospheric circulation; and (ii) to better define the frameworks and protocols for subsequent, and scientifically more ambitious, phases.

Due to the joint interest in high-resolution simulations, ESiWACE strongly supports and interacts with DYAMOND.
