Anthropogenic emissions and land use changes have modified atmospheric aerosol
concentrations and size distributions over time. Understanding preindustrial conditions and …

Multiphase chemistry plays a vital role in the Earth system, climate, and health. Chemical
reactions, mass transport, and phase transitions between gases, liquids, and solids are …

A major fraction of atmospheric aerosol particles, which affect both air quality and climate,
form from gaseous precursors in the atmosphere. Highly oxygenated organic molecules …

Secondary organic aerosol (SOA) accounts for a significant fraction of ambient tropospheric
aerosol and a detailed knowledge of the formation, properties and transformation of SOA is …

Isoprene is a significant source of atmospheric organic aerosol; however, the oxidation
pathways that lead to secondary organic aerosol (SOA) have remained elusive. Here, we …

Secondary organic aerosol (SOA), particulate matter composed of compounds formed from
the atmospheric transformation of organic species, accounts for a substantial fraction of …

New particle formation of liquid or solid nanoparticles from gas-phase precursors is a
decisive process in Earth's atmosphere and is considered one of the largest uncertainties in …

Air quality transcends all scales with in the atmosphere from the local to the global with
handovers and feedbacks at each scale interaction. Air quality has manifold effects on …

Recent field and laboratory evidence indicates that the oxidation of isoprene,(2-methyl-1, 3-
butadiene, C 5 H 8) forms secondary organic aerosol (SOA). Global biogenic emissions of …

Secondary organic aerosol (SOA) formation from the photooxidation of m-xylene, toluene,
and benzene is investigated in the Caltech environmental chambers. Experiments are …
