Research Abstract

Monitoring of the oxidative and reductive nitrogen species, NO_y, HNO_3, NO_3^- and NH_3, NH_4^+, has been performed at Cape Hedo, Okinawa, and their concentration levels, variability and its causes have been clarified. Comparing with the model-calculated concentrations by CMAQ chemistry-transport models, quantitative data base, which can be used as reference data for evaluating the nitrogen load to the area from the East Asian region, has been obtained. Also, the partitioning between gaseous and particulate phases of nitrates and ammonia and its controlling factors have been partly revealed.
