Ammonia (NH3) in ambient air was measured at Cape Hedo, Okinawa, in spring 2008 using a photo-acoustic spectroscopy method (TGA310, Omnisens). Average concentration and standard deviation (1σ) of NH3 was 0.56±0.50 ppbv. It is considered that the variation in NH3 concentration does not come from the long range transport. The concentration and standard deviation (1σ) of ammonium ion (NH4+) measured using an aerosol mass spectrometer (Q-AMS, Aerodyne) was 2.2±1.4 µgm-3 and NH4+ was more than 80% for NH3+NH4+ when NH4+ was transported over long-range associated with sulfate (SO42-). NH4+ was deficient when SO42-/(SO2+SO42-) was large in air masses.<br>
