     View Summary

    Lightning is an important source of nitrogen oxides (LNOx). The actual global production of LNOx is still largely uncertain. One of the reasons for this uncertainty is the limited available observation data. We measured the concentrations of total reactive nitrogen (NOy), nitric oxide (NO) and nitrogen dioxides (NO2) and then obtained NOx oxidation products (NOz: NOz=NOy - NOx) at a station at the top of Mount Fuji (3776ma.s.l.) during the summer of 2017. Increases in NOy and NO2 were observed on 22 August 2017. These peaks were unaccompanied by increases in CO, which suggested that the observed air mass did not contain emissions from combustion. The backward trajectories of the above air mass indicated that it moved across areas where lightning occurred. The NOy concentration was also calculated by using a chemical transport model, which did not take NOx produced by lightning into account. Therefore, the NOy concentration due to lightning can be inferred by subtracting the calculated NOy from the observed NOy concentrations. The concentration of NOy at 13:00 on 22 August 2017 originating from lightning was estimated to be 1.11 +/- 0.02 ppbv, which comprised 97 +/- 2% of the total NOy concentration. The fractions of NO2 and NOz in the total NOy were 0.54 +/- 0.01 and 0.46 +/- 0.03, respectively. The NO concentration was below the detection limit. We firstly observed increase of concentrations of NOy originating from lightning by ground-based observation and demonstrated the quantitative estimates of LNOx using model-based calculation.

     View Summary

    In this study, the original analyzer for measuring ozone reactivity, RO3, was improved and applied to field observations and analyses of RO3 of ambient air in a forest were conducted. It was found experimentally that the contribution of individually unmeasured VOCs like sesquiterpenes to RO3 was significant, especially in the summer daytime. It was also indicated that dependence analyses of RO3 on ambient temperature and light intensity could be useful for discussion on the situation of surrounding forests like tree species and BVOCs emission. Consequently, BVOCs analyses by RO3 measurements in ambient forest air were carried out successfully for the first time in the world. RO3 analyzer is a promising tool for studying BVOCs' behavior in the forest

     View Summary

    For evaluation of air quality such as secondary organic aerosols and photochemical oxidants, it is essential to know characteristics of productivity of organic nitrates (ONs) during the reaction of various volatile organic compounds (VOCs) with atmospheric radicals. In this study, we tried to establish a new method for measurement of ONs productivity based on a total ONs analyzer and the chemical perturbation technique. ONs productivities of a few VOCs were measured and relatively compared. Furthermore, quantitative determination of the branching ratio for ONs formation was successfully conducted. This method can be promising for improvement of the database of ONs productivities, especially for VOCs whose ONs productivities have not been reported yet

    揮発性有機化合物 VOCを前駆体とする大気中での二次有機エアロゾル粒子SOAの生成過程において、その中間生成物として有機硝酸類ANsが注目されている。本研究では、LIF-NO2を用いたANs全量計測装置を構築し、SOA生成過程におけるANsの挙動解明への貢献を目指す。前年度は、(1)TD-LIF法によるガス状有機硝酸全量計の構築、(2)フィルタ法やデニューダー法を組み合わせた粒子状ANs全量計測、(3)テフロンバッグを用いた初期的な反応実験におけるSOA中ANs全量の検出、を実現した。本年度は以下を実施した:(4)複数LIF装置による多試料同時計測法により、NO2やANsの同時またはモード切替による測定法を確立した。また、熱分解装置TDの温度設定に対する成分検出特性等を詳細に調べ、設定温度が妥当であることを確認した。(5)ピネン以外のVOC成分についても、反応実験と粒子状有機硝酸全量を測定し、実験例を蓄積した。有機硝酸全量の検出特性を成分ごとのラジカル反応特性と比較検証して、SOA生成について検討した。その結果、リモネン、α-ピネンはSOA(粒子状ANs)を多く生成したが、イソプレン・スチレン・シクロヘキサンは粒子状ANs生成量は小さかった。成分や濃度などの条件ごとに、粒子状ANs生成量を直接把握し、SOA生成を議論できるようにした。さらに、有機硝酸類ANs、ペルオキシアセチルナイトレート類PANs、NO2、などの窒素酸化物の内訳、およびそのガス-粒子分配比の定量にも成功し、ANsほかのSOA生成過程における内訳・分配比を知ることができるようになった。また、レーザーパーティクルカウンターによる生成SOA粒子数測定とも比較した結果、二次生成するANsがSOAの「成長」に寄与する場合があることを捕捉した。24年度が最終年度であるため、記入しない。24年度が最終年度であるため、記入しない

  • 植物起源揮発性有機化合物のオゾン反応性としての包括把握のための装置汎用化の試み

    2020  

     View Summary

    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. Recently, the RO3 analyzer has been applied to ambient observation in a forest atmosphere and BVOCs emission have been discussed. However, the analyzer is still not versatile due to ozone analyzers in the system. In order to realize field observations in various environments, it is necessary to construct the versatile RO3 monitor. In this study, fundamental experiments were conducted as follows: (1) Instead of highly sensitive ozone analyzers (handmade, chemiluminescence technique), less sensitive O3 monitors (commercial-based, UV absorption technique) were utilized to measure ozone reduction due to VOCs reactions. As a result of preliminary characterization and calibration of the prototype of versatile RO3 analyzer, the limit of detection reached 3 x 10-5 s-1 (S/N=3, 600-s average). (2) Then, as a practical test of the versatile RO3 analyzer, measurements of RO3 in the vapor sample of cryptomeria japonica leaf essential oil were demonstrated. The trace level signal of RO3 was captured. Consequently, it was confirmed experimentally that the versatile system could be promising for capturing BVOCs emission as RO3.
