英文摘要: Nitrous acid (HONO) plays important roles in tropospheric chemistry, but its source(s) are not completely understood. Here we analyze measurements of HONO, nitrogen dioxide (NO2 ), and related parameters at a coastal site in Hong Kong during September-December 2012. The nocturnal NO2 -to-HONO conversion rates were estimated in air masses passing over land and sea surfaces. The conversion rates in the "sea cases" (3.17-3.36 × 10-2 h-1) were significantly higher than those in the "land cases" in our study (1.20-1.30 × 10-2 h-1) and in previous studies by others. These results suggest that air-sea interactions may be a significant source of atmospheric HONO and need to be considered in chemical transport models. Key Points Strong HONO production in sea-coming air massesAir-sea interactions may significantly affect atmospheric chemistryChemical transport models may need to consider HONO production on the sea ©2014.
