Please see our new publication in Atmospheric Chemistry and Physics on the role of desorption lifetimes and activities on multiphase chemical kinetics. We also provide a parametrization to estimate desorption energies for implementation in multiphase chemical kinetics models: Knopf, D. A., Ammann, M., Berkemeier, T., Pöschl, U., and Shiraiwa, M.: Desorption lifetimes and activation energies […]

Nature has highlighted our recently published collaborative research article by Mamouri et al. showing that cirrus clouds forming over Cyprus (in the Mediterranean Basin) were triggered by wildfire smoke stemming from North America. The Nature highlight can be found here: Highlight article. Our research article can be accessed here: Research article.
