ICON-A: Roland Potthast
Description#
For the representation of the atmosphere, ICON includes a non-hydrostatic dynamical core operating on a icosahedral-triangular Arakawa C grid. Physics parameterizations for radiation, cloud microphysics (1- or 2-moment) and turbulence are always used, while orographic drag, subgrid cloud cover, and deep and shallow convection are parameterized or not depending on the configuration.
Model(s)#
ICON-A: atmospheric component of the ICON-ESM, open source license (BSD-3C).
Programming language(s)#
C++ PostScript
