dc.description.abstract | HONO photolysis is an early morning source of OH radicals in urban environment, which expedites the photooxidation of volatile organic compounds (VOC), leading to O-3 production. From July 14th to August 22nd 2018, HONO was measured at Korea University using a parallel plate diffusion scrubber coupled with Ion Chromatography (PPDS-IC), in conjunction with major reactive gases (O-3, NO, and NO2). The collection efficiency of PPDS was estimated as 91.8 similar to 99.9% from the side-by-side measurement. HONO mixing ratio ranged between 0.01 to 0.79 ppbv with a mean of 0.28 ppbv, which was higher in high-O-3 episode than non-episode. Likewise, the OH production from HONO photolysis was higher by 0.04 pptv sec(-1) in high-O-3 episodes, when the daily maximum O-3 exceeded 100 ppbv, than non-episode. The hourly maximum O-3 reached 170 ppbv under severe heat waves. When the diurnal variations of O-3 was simulated with the measured HONO using the Framework for 0-D Atmospheric Modelling (F0AM), the daily maximum O-3 changed by 8 similar to 17 ppbv according to the HONO and VOC levels. In particular, the daily maximum O-3 was increased under non-episode conditions with an increased HONO, albeit low level. | - |
