ICON-ART

 

ICON-ART, where ART stands for Aerosols and Reactive Trace gases, is an extension of ICON (ICOsahedral Nonhydrostatic model; developed at the German Weatherservice (DWD) and the Max-Plank-Institute of Meteorology Hamburg (MPI-M)) to enable the simulation of gases, aerosol particles and related feedback processes in the atmosphere. In its current stage, ICON-ART is capable of simulating mineral dust and sea salt aerosol and the interactions of these aerosol types with clouds. Additionally, in a joint development with German Weatherservice (DWD), the dispersion of volcanic ash particles and radioactive tracers has been made available for operational forecast. The Global Modelling Group (MOD) of IMK-ASF has introduced ozone depleting short-lived trace gases in the stratosphere, a linearized ozone chemistry and a photolysis module. For a further description of ICON-ART, see

Training course for the model system ICON-ART

The 2nd training course for the model system ICON-ART was held from October 12 to October 15, 2015 in the Hessian city Langen. It was organized in collaboration with the Institute for Meteorology and Climate Research (IMK) of the Karlsruhe Institute of Technology (KIT) and the German Weather Service (DWD). Nearly 30 participants provided an insight into the future weather prediction model ICON and performed initial simulations. They got information about the importance of aerosols (small liquid or solid particles suspended in the air) for weather patterns, aviation and climate in theory and practice.

The participants were able to perform simulations with ICON-ART. They calculated the dispersion of volcanic ash plumes by virtual eruption of different volcanoes, a simple ozone chemistry and a radioactive accidental release. Furthermore, the spread of sea salt particles could be simulated. Sea salt has a large share of the global aerosol amount and is assumed, among others, to play an important role for the formation of clouds.

We are pleased to repeat this course next year. The ICON-ART team Dipl.-Met. Daniel Rieger, M. Sc. Jennifer Schroeter, Dipl.-Met. Carolin Walter and Dr. Heike Vogel from KIT is led by Dr. Bernhard Vogel. The training course was supported by Dr. Florian Prill, Dipl.-Met. Jochen Förstner, Dr. Daniel Reinert from DWD.
