Outline of Final Research Achievements

We determined the triple oxygen isotopic compositions of tropospheric ozone from those in nitrate that had been produced on the nitrite-coated filters through the reaction between nitrite and ozone. We found that the triple oxygen isotopic compositions of tropospheric ozone taken in Nagoya were mostly larger than those taken in Niigata during the observation in winter.
