Output from ICON-LEM simulations around Ny-Aalesund (Svalbard). Includes mainly meteogram (hydrometeores, integrated values) and forcing data as well as the respective grids. The data is used in the publication "Large Eddy Simulations with the ICON-LEM in the complex Arctic environment around Ny–Ålesund" which focuses on a basic evaluation of the representation of mixed-phase clouds with the ICON-LEM at Ny-Aalesund.
