A correct and reliable forecast of volcanic plume dispersion is vital for aviation safety. This
can only be achieved by representing all responsible physical and chemical processes …

In June 2019, the Raikoke volcano, Kuril Islands, emitted 0.4–1.8× 10 9 kg of very fine ash
and 1–2× 10 9 kg of SO 2 up to 14 km into the atmosphere. The eruption was characterized …

Vast stretches of agricultural land in southern and central Africa are burnt between June and
September each year, which releases large quantities of aerosol into the atmosphere. The …

Volcanic aerosols change the atmospheric composition and thereby affect weather and
climate. Aerosol dynamic processes such as nucleation, condensation, and coagulation …

Southern West Africa (SWA) is undergoing rapid and significant socioeconomic changes
associated with a massive increase in air pollution. Still, the impact of atmospheric …

Emission inventories serve as crucial input for atmospheric chemistry transport models. To
make them usable for a model simulation, they have to be pre-processed and, traditionally …

Polar stratospheric clouds (PSCs) are a driver for ozone depletion in the lower polar
stratosphere. They provide surface for heterogeneous reactions activating chlorine and …

Atmospheric inverse modeling is the process of estimating emissions from atmospheric
observations by minimizing a cost function, which includes a term describing the difference …

Water uptake can significantly increase the size and therefore alters the optical properties of
aerosols. In this study, the regional-scale model framework COSMO-ART is applied to …

Atmospheric composition studies on weather and climate timescales require flexible,
scalable models. The ICOsahedral Nonhydrostatic model with Aerosols and Reactive Trace …
