Measurement report: Three-year characteristics of sulfuric acid in urban Beijing and derivation of daytime sulfuric acid proxies applicable to inland sites [PDF]

Atmospheric Chemistry and Physics
Sulfuric acid (H2SO4) is a key precursor in atmospheric new particle formation and cluster early growth. However, long-term measurement of it is only available at a few sites. Although several proxies for estimating H2SO4 concentration have been proposed,
