- 研究成果概要
- A unique system that uses the total reactivity with ozone (RO3) has been developed for measuring biogenic volatile organic compounds (BVOCs) emitted from vegetation into the atmosphere. However, the sensitivity of the prototype of RO3 analyzer was insufficient for measuring ambient atmosphere in the forests. In this study, the improvement of RO3 analyzer was explored, especially focused on the improvement of the fast-response chemiluminescent ozone analyzer, CLD-O3. Consequently, the sensitivity of CLD-O3 was achieved. However, the noises were still large at present. The upper limit of quantifiable ozone ratio ([O3(VOC)]/[O3(VOC=0)] was not improved drastically. As a next step, continuing improvement of analyzers, including reduction of noises by cooling the photomultiplier of CLD-O3, is essential.
