Stratospheric ozone depletion through catalytic chemistry involving man‐made
chlorofluorocarbons is an area of focus in the study of geophysics and one of the global …

Soot particles, composed of elemental carbon and organic compounds, have attracted
widespread attention in recent years due to their significant impacts on climate, the …

Ozone is produced in the troposphere by gas-phase oxidation of hydrocarbons and CO
catalyzed by hydrogen oxide radicals (HOx≡ OH+ H+ peroxy radicals) and nitrogen oxide …

Photochemical smog, or ground-level ozone, has been the most recalcitrant of air pollution
problems, but reductions in emissions of sulfur and hydrocarbons may yield unanticipated …

Heterogeneous and multiphase reactions on solids and in liquids, respectively, have the
potential to play a major role in determining the composition of the gaseous troposphere and …

Polluted air masses are characterized by high concentrations of oxidized nitrogen
compounds which are involved in photochemical smog and ozone formation. The OH …

We present a new global three‐dimensional chemical‐transport model (called MOZART)
developed in the framework of the NCAR Community Climate Model (CCM) and aimed at …

Soot particles produced by incomplete combustion processes are one of the major
components of urban air pollution. Chemistry at their surfaces lead to the heterogeneous …

During the 20th century, the world's transportation system has changed dramatically with the
gradual emergence of a large fleet of commercial aircraft. Today, thousands of aircraft carry …

The first simultaneous measurements and analytical data on atmospheric concentrations of
PM2. 5, PM10, inorganic constituents, carbonaceous species, and their optical properties …
