Organic nitrogen compounds (ONCs) emitted from combustion sources, agricultural activities and biogenic processes undergo a complex array of oxidation reactions in the atmosphere. Gas-phase reactions ...

Criegee intermediates (CIs)—highly reactive species formed when ozone reacts with alkenes in the atmosphere—play a crucial role in generating hydroxyl radicals (the atmosphere's "cleansing agents") ...

Hydroperoxides are strong oxidants that have a significant influence on chemical processes in the atmosphere. Now, an international research team involving the Leibniz Institute for Tropospheric ...

The atmosphere and the earth’s ecosystems are parts of a coupled system. For a large variety of processes, forcing from one partner in the interaction elicits one or more responses from the other ...

The first deployment of one of NASA’s most ambitious research studies of Earth’s atmosphere will take place this July and August. The Atmospheric Tomography mission will take off aboard the agency’s ...
