Research Abstract |
Temporal variation in the triple oxygen isotopic compositions of atmospheric nitrate in precipitation (wet deposition) was monitored continuously in four observatories in Japan (Rishiri, Sado-seki, Kosugi, and Minami-torishima). We concluded the triple oxygen isotopic compositions of atmospheric nitrate were the useful tracer to estimate the major photochemical reaction path from NO to nitrate in eastern Asian troposphere. Besides, we found that the annual average values in the triple oxygen isotopic compositions of atmospheric nitrate was almost stable in mid-latitudes.
