DYAMOND

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.

 

Overview

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.

 

Participating Groups/Model Information and Contacts

DYAMOND started as a joint initiative between the MPI-M (Bjorn Stevens) and University of Tokyo (Masaki Satoh). Further impulse was given through the involvement of US participants (Chris Bretherton, University of Washington), the support of DWD through the HErZ project (Daniel Klocke) and with the help of organisational support from DKRZ in the scope of the ESiWACE project (Joachim Biercamp, Philipp Neumann). Participating models are listed below along with the models' main scientific/technical contact. For further information about DYAMOND please contact either or .

Input Data

Initial Data (1 Aug 2016)

A IFS grib file with initial data for 1 August 2016 is provided here. To process the data, you may use cdo or eccodes.

A NetCDF file, basically equivalent with the grib input, is provided here.

Alternatively, the initial data can be directly retrieved from the MARS database at ECMWF using this request.

SST and Sea Ice

IFS data (7 day means) are provided here.

 

Registration

Groups interested in joining the intercomparison project are welcome. To register and scope out details on the work, interested groups please contact the , including the following information: (a) which model shall be investigated and (b) details of a contact person.
