Explosive Volcanic Eruptions

Explosive volcanic eruptions influence the global climate on time scales of months to years depending on the amount of sulfur species injected into the stratosphere. The direct injection of volcanic gases modifies microphysical and chemical processes in the stratosphere which may lead to ozone destruction. Volcanic ashes determine the plume development and therefore the amount of volcanic gases reaching the stratosphere.

Biomass Burning

ATHAM is employed for the simulation of plumes developping over vegetation fires. Jörg Trentmann at the Max-Planck-Institute for Chemistry in Mainz has implemented a radiation scheme and developed a module which describes the gas phase chemistry in the plume.
