nextGEMS Cycle 1
----------------
The Cycle 1 simulations are based on the `DYAMOND Winter simulations <../Winter/index.html>`_, but run for one year at about 5 km horizontal resolution and for 2 to 3 months at 2.5 km resolution. Within Cycle 1, first bugs were detected and fixed such that some further runs are available with improved configuration.

Please find here an `overview of the processed variables of Cycle 1 <../../_static/DYAMOND/NextGEMS/variable_table.html>`_

IFS
~~~

Here's a first overview of the IFS Cycle 1 simulations:

ICON
~~~~
The original Cycle 1 simulation from ICON developed out of the latest DYAMOND-Winter run (`dpp0029`) and is called `dpp0052`.
This simulation was analyzed during the nextGEMS Cycle 1 Hackathon in October 2021.

Continuous development and especially the transition from the old (Mistral) to the new (Levante) supercomputer lead to significant workflow improvements (new compiler, new scripting).
The `dpp0066` (5 km) and `dpp0067` (2.5 km) runs are the latest Cycle 1 simulations run on Levante. They include improvements on the model physics such as a bug fix for the surface wind stress over the ocean.
A publication describing these simulations will be submitted end on June 2022.
Those runs also served as a basis for a student hackathon at UCM (Madrid) in April 2022.
