Atmospherically Relevant Chemistry and Aerosol box model – ARCA box (version 1.2) [PDF]

open access: yesGeoscientific Model Development, 2022
We introduce the Atmospherically Relevant Chemistry and Aerosol box model ARCA box (v.1.2.2). It is a zero-dimensional process model with a focus on atmospheric chemistry and submicron aerosol processes, including cluster formation.

Nighttime atmospheric chemistry of iodine [PDF]

open access: yesAtmospheric Chemistry and Physics, 2016
Little attention has so far been paid to the nighttime atmospheric chemistry of iodine species. Current atmospheric models predict a buildup of HOI and I2 during the night that leads to a spike of IO at sunrise, which is not observed by measurements ...

Modeling the Unimolecular Decay Dynamics of the Fluorinated Criegee Intermediate, CF3CHOO

open access: yesPhotochem, 2023
When volatile alkenes are emitted into the atmosphere, they are rapidly removed by oxidizing agents such as hydroxyl radicals and ozone. The latter reaction is termed ozonolysis and is an important source of Criegee intermediates (CIs), i.e., carbonyl ...
