 event
 The delta(O2/N2)cor. of sample air is determined against a reference air using a mass spectrometer. The delta(O2/N2)cor. of our primary standard air (cylinder No. CRC00045) is determined against a reference air every 2 month. Finally, the delta(O2/N2)cor. of sample air is determined against the primay standard air. The measurement method is detailed in Ishidoya & Murayama (2014 Tellus B).

 Operational/Reporting
 Air samples were collected into 24 titanium flasks using manual air sampling pump from Atsugi Air Base to Minamitorishima. Some of them have been analyzed for delta(O2/N2) and delta(Ar/N2), as well as the stable isotopic ratios of N2, O2 and Ar. The delta(O2/N2)cor. presented here are the delta(O2/N2) values corrected for an artificial fractionation of O2 and N2 by using simultneously-measured delta(Ar/N2), following the method described in Ishidoya et al. (2014 SOLA).
