Lightning Source of Nitrogen Oxides (NO x ) Inferred From Geostationary Satellites: Global Implications for Oxidant Chemistry

Abstract Lightning is a major source of nitrogen oxide radicals (NO x ≡ NO + NO 2 ), but large uncertainties in NO x yields per flash hinder accurate quantification of emissions and impacts on oxidant chemistry. We use 1 year of concurrent geostationary satellite observations of...

Space‐Based Observation of Decadal Variations of Ammonium Sulfate Aerosols Over Northern China

Abstract The concentrations of ammonium sulfate, an important component of secondary inorganic aerosols, have dropped substantially in the North China Plain (NCP) over the past decade. However, current understanding of its variations is limited by the small number of ground‐based...
