MECCA-based (full) Chemistry

- work in progress -

In this configuration example a simulation with (full) MECCA-based chemistry is performed. If we talk about MECCA-based chemistry we mean a full gas phase chemistry that can be applied additionally to the existing standard parametrized chemistry from ICON-ART (explained in the article Atmospheric Chemistry, example: click here). MECCA uses the Kinetic PreProcessor (KPP) to convert the chemical equations into differential equations that can be used then e.g., in ICON-ART. MECCA already contains a comprehensive chemical mech- anism, but it also allows to create an own mechanism by changing equations or only picking a subset of equations. To perform this example, a complete reaction mechanism is created and transferred to ICON-ART.

This article teaches you...

• the implementation of (full) MECCA-based chemistry in ICON-ART
• the creation of a chemical mechanism and the selection of the respective desired chemical species and their reactions in MECCA
• the implementation of not yet in MECCA implemented reactions in your mechanism
• the creation of the to your mechanism belonging Mecca-xml data to link MECCA calculations with ICON-ART
