NH3 release during the evaporation of different types of atmospheric precipitation: A case study in Changchun, China

Scientific Reports
Ammonia (NH3) is a key precursor of secondary inorganic aerosols. During precipitation, NH3 in the atmosphere can be captured by rain and converted to NH4 +, whereas during evaporation, NH4 + can become NH3 and be released again.
