Chemical Coupling Between Atmospheric Ozone and Particulate Matter [PDF]
, 1997 A major fraction of ambient particulate matter arises from atmospheric gas-to-particle conversion. Attempts to reduce particulate matter levels require control of the same organic and nitrogen oxide (NO_x) emissions that are precursors to urban and ...

Relating hygroscopicity and composition of organic aerosol particulate matter [PDF]
, 2010 A hygroscopicity tandem differential mobility analyzer (HTDMA) was used to measure the water uptake (hygroscopicity) of secondary organic aerosol (SOA) formed during the chemical and photochemical oxidation of several organic precursors in a smog chamber.
