Robust air pollutant emission reduction strategies rely on accurate source characterizations. Studies have reported that the methane (CH4) emissions from California’s dairy sector are highly variable, and raised questions regarding the representati

Recent work has identified nitric acid (HNO3) as a potential precursor of nitrous acid (HONO), which is an important source of oxidants that regulate ozone and particulate pollution. Recent work in our laboratory has indicated that the reduction of H

We present field observations made in June 2011 downwind of Dallas-Fort Worth, TX, and evaluate the role of stabilized Criegee radicals (sCIs) in gaseous sulfuric acid (H2SO4) production. Zero-dimensional model calculations show that sCI from biogeni

Simultaneous high-time-resolution measurements of atmospheric NH3 ,H NO3, soluble gas-phase chloride, and aerosol species were made in Houston, TX, from August 5, 2010 to August 9, 2010. Gaseous NH3 was measured using a 10.4-mm external cavity quantu
