説明

This study applies the chemistry version of the Weather Research and Forecasting model (WRF-Chem) to examine impacts of three additional HONO sources, i.e., the reaction of photo-excited NO2 (NO2*) with water vapor (NO2* chemistry), the NO2 heterogeneous reaction on aerosol surfaces and HONO emissions, on concentrations and deposition of individual NOy species over the Beijing-Tianjin-Hebei region (BTH) in summer and winter periods of 2007. The results show that the three additional HONO sources produce a 20%∼40% (> 100%) increase in monthly-mean OH concentrations in many urban areas in August (February), leading to a 10%∼40% (10%∼100%) variation in monthly-mean concentrations of NOx, NO3− and PAN, a 5%∼10% (10%∼40%) increase in the total dry deposition of NOy, and an enhancement of 1.4 Gg N (1.5 Gg N) in the total of dry and wet deposition of NOy over this region in August (February). These results suggest that the additional HONO sources aggravate regional-scale acid deposition, emphasizing the importance of the additional HONO sources in the NOy budget.
