Modelling of the interaction between radiation and the atmospheric composition with ICON-ART

Schröter, Jennifer Jasmin

Abstract (englisch):
This thesis presents the modelling of the interaction of radiation and the
composition of the Earth's atmosphere with the next generation modelling system
ICON-ART. The ICOsahedral Non hydrostatic model with Aerosols and Reactive
Trace gases (ICON-ART) provides a suitable environment for atmospheric
composition studies on weather and climate time scales.

Most global climate models or numerical weather prediction models use simplifications in solving the radiative transfer equation to save computational time.
In this thesis, the validation of a more advanced module for solving the
radiative transfer equation is presented. This module allows a consistent
treatment of the actinic flux calculation and also the radiative net flux calculation.
For the first time, photolysis rate calculations are performed
with the technique of local grid refinement of ICON. For validation,
aircraft campaign data are compared to ICON-ART simulations on a statistical
basis. Furthermore, the question on the quantification of the
radiative impact of clouds on photolysis rates is addressed.

The second part of this thesis focuses on the ... mehr
