Awards

  • 2017年度 大気環境学会誌最優秀論文賞

    2017.9   大気環境学会   2014年5月の黄砂イベントを地上・衛星観測とモデルにより統合的に解析した論文であり、黄砂時の粒子状硝酸塩の越境寄与率を推定するなど、その成果は学術的な価値にくわえて、適時性ならびに社会的意義の点でも高く評価された。

  • 2017年度環境賞 優良賞

    2017.6   国立環境研究所   東アジアは大気汚染発生量が多く、大気浮遊粒子状物質濃度が世界で最も高い地域の一つである。黄砂と人為起源の大気汚染粒子が混在する特徴的な地域でもある。大陸で発生するこれらの粒子は、西風に乗って日本に輸送される。国内の大気汚染対策を講じる上で、越境輸送によって飛来する粒子状物質の動態を理解し、監視することが重要である。このようま背景からライダー(レーザーレーダー)を用いた大気浮遊粒子観測網と化学輸送モデルによる飛来予測システムを開発した。

    We improved two-wavelength polarization Mie-scattering lidars at several main sites of the Asian dust and aerosol lidar observation network (AD-Net) by adding a nitrogen Raman scatter measurement channel at 607 nm and have conducted ground-based network observation with the improved Mie–Raman lidars (MRL) in East Asia since 2009. This MRL provides 1α+2β+1δ data at nighttime: extinction coefficient (α532), backscatter coefficient (β532), and depolarization ratio (δ532) of particles at 532 nm and an attenuated backscatter coefficient at 1064 nm (βat,1064). Furthermore, we developed a Multi-wavelength Mie-Raman lidar (MMRL) providing 2α+3β+2δ data (α at 355 and 532 nm; β at 355 and 532; βat at 1064 nm; and δ at 355 and 532 nm) and constructed MMRLs at several main sites of the AD-Net. We identified an aerosol-rich layer and height of the planetary boundary layer (PBL) using βat,1064 data, and derived aerosol optical properties (AOPs, for example, αa, βa, δa, and lidar ratio (Sa)). We demonstrated that AOPs cloud be derived with appropriate accuracy. Seasonal means of AOPs in the PBL were evaluated for each MRL observation site using three-year data from 2010 through 2012; the AOPs changed according to each season and region. For example, Sa,532 at Fukue, Japan, were 44±15 sr in winter and 49±17 in summer; those at Seoul, Korea, were 56±18 sr in winter and 62±15 sr in summer. We developed an algorithm to estimate extinction coefficients at 532 nm for black carbon, dust, sea-salt, and air-pollution aerosols consisting of a mixture of sulfate, nitrate, and organic-carbon substances using the 1α532+2β532 and 1064+1δ532 data. With this method, we assume an external mixture of aerosol components and prescribe their size distributions, refractive indexes, and particle shapes. We applied the algorithm to the observed data to demonstrate the performance of the algorithm and determined the vertical structure for each aerosol component.

  • Optical properties of mixed aerosol layers over Japan derived with multi-wavelength Mie–Raman lidar system Reviewed

    Mixing state of aerosols and optical properties including lidar ratio, particle depolarization ratio, and Ångström exponent were investigated at Fukuoka in western Japan using a multi-wavelength Mie–Raman lidar (MMRL), various aerosol mass-concentration measurements, and a polarization optical particle counter during Winter–Spring 2015. Aerosol extinction coefficient, backscatter coefficient, and depolarization at 355 and 532 nm and attenuated backscatter coefficient at 1064 nm are obtained from the MMRL measurements. Ten aerosol episodes were classified into three categories (air pollution, mineral dust, and marine aerosol) based on aerosol mass-concentration measurements in the fine-mode (particle diameter Dp<2.5 μm) and coarse-mode (2.5 μm<Dp<10 μm). The mean lidar ratio for air pollution was 57±4 sr at 355 nm and 53±8 sr at 532 nm with Ångström exponent of 1.4±0.5. For mineral dust, a slightly high averaged lidar ratio (50±7 sr at 355 nm and 54±9 sr at 532 nm) was obtained with relatively high Ångström exponent of 0.8±0.3 owing to contributions from fine-mode particles (PMf). The mean particle depolarization ratios of 13±8% at 355 nm and 16±6% at 532 nm also suggest mixing of mineral dust and anthropogenic fine-mode aerosols. The lowest lidar ratio was obtained for marine case. Classification of aerosol types using the lidar ratio and particle depolarization ratio was conducted based on the results obtained in this study. The classified aerosol types almost corresponded to aerosol category obtained by previous studies. We found no remarkable correlation between the fraction of black carbon and the lidar ratio: this might be due to the complexity of the mixing state among various aerosols. The obtained lidar ratio was rather correlated with the ratio of PMf to PM10, representing the mixing state of fine- and coarse-mode particles.

    東アジア域ではPM2.5の減少傾向が観測されているにも関わらず、対流圏オゾン濃度の上昇が問題となっており、その要因は未だ明らかでない。一方気象場の長期的な変化としては、地球温暖化による気温上昇等が顕在化している。温暖化に伴う気象場の変化とオゾンの増加の関連性を明らかにすることは、今後の温暖化環境下での大気質を予測し、オゾンの前駆物質の削減対策を立案する上で重要である。本研究では2000-2022年の東アジア域に着目し、対流圏オゾンおよび気象要素の長期観測データから高温およびオゾン高濃度イベントを抽出し、温暖化に伴う気象場の変化が対流圏オゾン濃度へ及ぼす影響を数値モデルにより定量的に評価する。

    アジア域の主要な大気汚染物質の発生源からの流れを把握するために緯度帯・気候帯を代表する3地点に同じ機能を持つ多波長のラマン・ミー散乱ライダーを展開し、エアロゾル組成・空間分布を連続測定し、黒色炭素(BC)成分を含むエアロゾルの組成を高精度でリトリーバルするアルゴリズムを開発する。観測値を拘束条件として多成分同時化学輸送インバースモデルを構築し、高精度のBCや人為起源エアロゾルの5次元(時間・地点・組成)のエアロゾル分布の再解析データベースを作成する。これをもとに、エアロゾルの気候影響評価の高精度かを目指す。
