| 摘 要： | Nitrous acid(HONO) is an important source of hydrogen oxides(HOx), which affects air quality, the atmospheric oxidation capacity, and human health. Here, we present ambient measurements of the HONO concentrations in Zhuhai, a coastal city in Southern China,from February 7 to March 15, 2021. The campaign was classified into two periods during(P1) and after(P2) the Spring Festival holidays. The average HONO mixing ratio during P2(1.19 ± 0.85 ppbv) was much higher than that during P1(0.24 ± 0.18 pp...
