DYAMOND Summer simulations are experiments of forty days and forty nights, beginning on 1 August 2016, using global models with a storm-resolving grid spacing of 5 km or less. Detailed information can be found in the DYAMOND experiment protocol (pdf).
The simulations were completed by May 2018 and nine different groups from six national entities across three continents submitted results. They have demonstrated that such simulations are nowadays feasible.

Accessing the data
For data analysis, ESiWACE provides compute resources and infrastructure at the German Climate Computing Center (DKRZ). Detailed model, experiment and output descriptions as well as tutorials, scripts and tips for analysing high-resolution climate simulation output are provided on our user documentation page https://easy.gems.dkrz.de.
If you work with the data stored at DKRZ, we request that you acknowledge DKRZ and ESiWACE in any publication resulting from this work.
If you are interested in accessing the DYAMOND Summer data, please contact the ESiWACE coordination team.

Contributions are no longer accepted.
Simulation setup, model output and data policy are specified in the DYAMOND experiment protocol (pdf). It has been kept as simple as possible to encourage participation and to ensure a fast turnaround.
Initial Data for 1 August 2016
As initial and boundary data, daily sea-surface temperatures as well as a global meteorological analysis taken from the European Center for Medium-Range Weather Forecasts (ECMWF) are provided.
-
A IFS grib file with initial data for 1 August 2016 is available from DKRZ. To process the data, you may use cdo or eccodes.
-
A NetCDF file, basically equivalent to the grib input, is available from DKRZ.
-
Alternatively, the initial data can be directly retrieved from the MARS database at ECMWF using this request.
-
Data for Sea Surface Temperature and Sea Ice: IFS data (7 day means) are available from DKRZ.
