Reactivit'Air

An important part of my Academy Research Fellow project (2017-2022) funded by Academy of Finland was the development of an instrument to measure total ozone (O3) reactivity. The paper describing the method we use, based on an idea by Dr. Detlev Helmig, and developed together with his group, has just been published in Atmospheric Measurement Techniques . At the time of my proposal submission in 2016, there had been only one publication on the topic of total O3 reactivity measurement by Prof. Jun Matsumoto (Waseda University, Tokyo, Japan). I was also aware of measurements that had been done by Dr. Helmig's group that had been presented at conferences. This is why I visited Prof. Matsumoto in Tokyo in December 2017 and then went to Boulder CO, U.S.A. , with Anssi Liikanen , in January 2018. Anssi stayed almost two months to work in Dr. Helmig's laboratory, performing many tests on the total O3 reactivity monitor (TORM).   Figure 1. Left: TORM at the Toolik Field Station, Alaska...

International collaboration is a cornerstone of modern science. This is why funding agencies generally make mobility an important part of any funding application. Academy of Finland is not different and my Academy Research Fellow project includes several instances of mobility. As I was preparing my proposal including ozone reactivity measurements, I was made aware of the unpublished work from Prof. Detlev Helmig and his team on this topic at the  Atmospheric Research Laboratory (ARL) , part of the  Institute for Arctic and Alpine Research (INSTAAR) at the University of Colorado in Boulder. After contacting Prof. Helmig, he agreed to host a laboratory visit in order for me to get familiar with their method. As the project got funded, the visit was settled for the beginning of 2018. Therefore, after visiting Prof. Matsumoto in Tokyo , I embarked on another trip, this time to the United States of America, and this time together with Anssi . I stayed for three weeks the...
