The ICOsahedral Nonhydrostatic model with Aerosols and Reactive Trace gases (ICON-ART) is a state-of- the-art modelling system for the simulation of interactions between atmospheric composition and circulation. It can be used across a wide variety of spatial and temporal scales, e.g. from weather to climate time scales. We present the latest results of simulations in the context of the POLSTRACC campaign. Here, we used the two-way nesting technique with a global domain resolution of 40 km and a nested domain with 20 km. The second part of this talk focusses on decadal integrations using a simple stratospheric chemistry scheme in conjunction with the climate physics configuration of ICON-ART.
Across scales: Modelling of the interactions between physics and atmospheric composition with ICON-ART
Antarctic total ozone column (DU) for a time sequence starting on 21 September 2002 finishing 1 October 2002 (left to right). Daily averages for two ICON-ART simulations for the Linoz chemistry scheme (a–d) and for the extended Chapman cycle chemistry (e–h). Total Ozone Mapping Spectrometer (TOMS) observations are shown in panels (i–l). The model was initialised on 20 September 2002.
Jennifer Schröter is a physicist working as a PostDoc at KIT in the group of Prof.Dr. Peter Braesicke. In her PhD thesis (2017) she focused on the modelling of the interaction of radiation and the composition of the Earth’s atmosphere with the next generation modelling system ICON-ART. In the scope of the ESM project, she is working on the development of flexible interfaces incorporating e.g. the assimilation framework PDAF in CON-ART.
