After a huge resonance for the first experiment, DYAMOND Winter proposes two additional experiments, which will complement the boreal summer period with a winter period. In the second phase, the experiment will be conducted with both atmosphere only and (if possible) with coupled atmosphere-ocean models, beginning on 20 January 2020 and running until 1st March 2020. Detailed information can be found in the DYAMOND Winter experiment protocol (pdf).

Accessing the data

For data analysis, ESiWACE provides compute resources and infrastructure at the German Climate Computing Center (DKRZ). To simplify the analysis and to ease comparisons, our team at ESiWACE standardises most of the incoming DYAMOND Winter data sets and includes them in an intake-esm catalogue. 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

If you work with the data stored at DKRZ, we request that you acknowledge DKRZ and ESiWACE in any publication resulting from this work.

Contributing to the project

Contributions are still being accepted.

Simulation setup, model output and data policy are specified in the DYAMOND Winter experiment protocol (pdf). To ensure smooth operation of the DYAMOND Winter data collection, we kindly ask you to adhere to the DYAMOND Winter Data request (pdf) as much as possible.
