What is it about?
Oxygen isotopic ratio of ozone has large enrichment and is a key tracer for material circulation in the stratosphere. We found, for the first time, that the ozone photolysis of ozone and asymmetric-18 ozone generated a sharp diurnal variation of oxygen isotopic ratio of them, in contrast to the temporal variation of concentration of ozone.

Why is it important?
Atomic oxygen is a key oxidant for greenhouse gases such as H2O, CH4, and N2O whose amounts are currently increasing in the stratosphere. Ozone photolysis is a major source of atomic oxygen generation. Our work forwarded toward accurate estimating of oxygen isotopic ratio of atomic oxygen and it leads more accurate prediction of the future climate change.
Perspectives
I feel I could grow as a scientist through writing this article. I deeply thought about what a meaning of publication is and why publication is important. It was great pleasure and valuable in the early-carrer scientist like me. I believe this article is one of my memorial one for all my life as a scientist.
