We conducted 1-year continuous measurement of HONO at the SORPES station. We obtained seasonal and diurnal variations of HONO and evaluated the contribution of HONO photolysis to OH radical and the missing daytime source of HONO. We separated the sources of nocturnal HONO into four parts: combustion emissions, soil emission, formation on ground and formation on aerosol, and estimate their contribution semi-quantitatively. The results highlighted ever-changing contributions of HONO sources.
