The cycling of inorganic bromine in the marine boundary layer (mbl) has received increased
attention in recent years. Bromide, a constituent of sea water, is injected into the atmosphere …

Aircraft observations from three recent missions (STRAT, SUCCESS, SONEX) are
synthesized into a theoretical analysis of the factors controlling the concentrations of HOx …

Theory and experiment have built insightful models for gas phase reactions and their
dynamics. However, a high level of complexity is added to this problem by intermolecular …

Hydroxyl radicals are often called the “detergent” of the atmosphere because they control
the atmosphere's capacity to cleanse itself of pollutants. Here, we show that the reaction of …

Chemical ionization mass spectrometry (CIMS) has proven to be a powerful method for
sensitive, fast time response (t∼ 1 sec) measurements of various atmospheric compounds …

The factors controlling the concentrations of HOx radicals (= OH+ peroxy) in the upper
troposphere (8–12 km) are examined using concurrent aircraft observations of OH, HO2 …

Atmospheric field measurements and models of the stratospheric sulfate aerosol layer led to
the suggestion that sulfuric acid (H2SO4) must photolyze at high altitudes. We propose that …

Intermolecular interactions in molecular clusters can significantly alter the optical properties
and reaction dynamics of the constituent monomers. As a result, both atmospheric chemistry …

Ozone is a major source of OH radicals in the troposphere. It is well-known that
photodissociation of ozone is key for the conversion of ozone into OH radicals. In the present …

Reactive nitrogen oxides play key roles in the photochemistry of the upper troposphere and
lower stratosphere (UT/LS). Significant progress has occurred in the last decades in both the …
