This page gives a short overview of selected experiments with the pathes to the directories where the output is stored.

**Note that the volume of data is very large for this kind of simulations. Users should only copy to the workspace/scratch the variables they really need for their analysis.**


===== 1. DYAMOND ====

DYAMOND stands for The DYnamics of the Atmospheric general circulation Modeled On Non-hydrostatic Domains, and it was the first ever intercomparison of global-storm-resolving models.  Nine models participated, run for 40 days (1.8-10.9.2016), with a great number of simulations performed with ICON (NWP version). A general overview of DYAMOND is given in Stevens et al. 2020 [[https://progearthplanetsci.springeropen.com/articles/10.1186/s40645-019-0304-z | doi]] and a more specific presentation of the ICON results in Hohenegger et al. 2020 [[https://www.jstage.jst.go.jp/article/jmsj/98/1/98_2020-005/_article | doi]]. More technical information on the participating models can also be found on the ESiWACE DYAMOND website ([[https://www.esiwace.eu/services/dyamond | website]]).

===== 2. ICON-LEM simulations over Germany =====

As part of the HD(CP)2 project ([[http://hdcp2.eu/]]), simulations with the ICON Large-Eddy Model have been performed over Germany with grid spacings of 625, 312 and 156 m for selected days. The ICON-LEM code is documented in Dipankar et al. 2015 [[https://agupubs.onlinelibrary.wiley.com/doi/abs/10.1002/2015MS000431 | doi]] and overview of the simulations are given in Riecke et al. 2017 [[https://rmets.onlinelibrary.wiley.com/doi/full/10.1002/qj.2947 | doi]] and Stevens et al. 2020 [[https://www.jstage.jst.go.jp/article/jmsj/98/2/98_2020-021/_article | doi]].

===== 3. NARVAL simulations =====

As a support to the NARVAL two field campaigns, ICON simulations (NWP version) have been performed over the tropical Atlantic. Storm-resolving simulations with a grid spacing of 2.5 km over the whole tropical Atlantic basin with a local grid refinement of 1.25 km over the western basin have been performed for December 2013 (NARVAL) and August 2016 (NARVALII). Those simulations are documented in Klocke et al. 2017 [[https://www.nature.com/articles/s41561-017-0005-4 | doi]]. Large-eddy simulations with a grid spacing of 1250, 600, 300 and 150 m have been performed over the western Atlantic for selected days and are documented in Stevens et al. 2019 [[https://doi.org/10.1175/BAMS-D-18-0198.1 | doi]].
