DYAMOND Summer simulations are experiments of forty days and forty nights, beginning at 1 August 2016, using global models with a storm resolving grid spacing of 5 km or less. Detailed information can be found at the DYAMOND protocol (pdf).

Completion of the simulation had been done until May 2018 and nine different groups from six national entities across three continents submitted results and demonstrated that such simulations are nowadays doable.

Contributing to the project

The DYAMOND protocol (pdf) specifies the simulation setup and the model output and data policy. It was kept as simple as possible to encourage participation and ensure a fast turn-around.

Initial Data for 1 August 2016

As initial and boundary data, daily sea-surface temperatures as well as global meteorological analysis taken from the European Center for Medium Range Weather Forecasts (ECMWF) are provided.

  • 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.
