The ICON Single-Column Mode

The single-column mode (SCM) of the ICON (ICOsahedral Nonhydrostatic) modeling framework is presented. primary purpose SCM to use it as a tool for research, model evaluation and development. Thanks simplified geometry SCM, various aspects model, in particular physics, can be studied well-controlled environment. Additionally, has reduced computational cost low data storage demand. utilized idealized cases—several well-established cases are already included—or semi-realistic based on analyses or forecasts. As case setup defined by single NetCDF file, new prepared easily modification this file. We demonstrate usage different such shallow convection, stratocumulus clouds, radiative transfer. tested together with an equivalent three-dimensional large eddy simulation ICON. Such consistent comparisons across hierarchy configurations very helpful will implemented into operational serve additional advancing development model.
