Dear Colleagues,

Iron is the most abundant transition element in the atmosphere, existing as multiple oxidation states and acting as a catalyst for red-ox reactions. Therefore, iron is associated with the production of reactive oxygen species both in environmental and biological systems and plays an important role in many geochemical cycles, including that of carbon and sulfur. With iron solubility largely controlled by its oxidation state and its chemical reactivity largely controlled by solubility, the theme of this Special Issue focuses on how iron speciation, oxidation state, and atmospheric transformations affect iron solubility and reactivity. As iron solubility is key to atmosperic iron’s chemistry, this Special Issue focuses on understanding the origins of atmospheric iron solubility, both from the standpoint of emission sources and transformations during atmospheric transport. Although not restricted to these issues, topics related to the following are of interest:

Iron speciation, oxidation state, and solubility measurements in both ambient atmospheres and from specific sources;
Laboratory experiments modeling iron behavior and chemistry under relevant atmospheric conditions;
Atmospherically relevant chemical reactions between iron and organic compounds.

By bringing these topics together, we hope to integrate the current state of knowledge of both iron emissions and iron transformations, painting a more complete picture of how iron contributes to atmospheric chemistry.
