| 1 | BALLOON-BORNE MEASUREMENTS OF AEROSOL VERTICAL DISTRIBUTIONS OVER BEIJING DURING THE SUMMER AND AUTUMN OF 1993显示文摘The results of two balloon soundings during the summer and autumn of 1993 from the Xianghe Observation Stationare being utilized in a study of the temporal and spatial distribution of the atmospheric aerosols.The balloon,gondola,instrumentation and atmospheric conditions during the observation period are described.The temporal and spatialcharacteristics of aerosol concentration,size ratio,mixing ratio,and size distribution for both troposphere and strato-sphere are presented and analyzed. | 周军 谭锟 邵石生 龚知本 石广玉 郭建东 王标 张豹武 孙宝来 Yasunobu Iwasaka Masahiko Hayashi Masahiro Hase | 1994 | Acta meteorologica Sinica1994，8，4： | 3 |
| 2 | Aerosol optical properties derived from simultaneous sunphotometer and aureolemeter measurements in Lhasa显示文摘In order to obtain some aerosol properties in Tibetan Plateau atmosphere, simultaneous measurements of aerosols by use of a sunphotometer and an aureolementer were performed in the summer of 1998 in Lhasa(29.65°N, 91.13°E). Optical depth, volume size distribution and phase\|function of aerosols were obtained from the measurements. Religious activities can have an effect on optical depth in Lhasa. The daily average aerosol optical depth( λ =500 nm) is less than 0.2. The diurnal variations of aerosol optical depth are relatively small during the period of summer. The maximal value of the mode radius in the volume size distribution are about 0.4, 2.0 and 4.0μm. | BAI Yu\|bo\+1, SHI Guang\|yu\+\{1*\}, Koichi Tamura\+2, Takashi Shibata\+2, Yasunobu Iwasaka\+2, Kaneta Shin′ichi\+3, Takamura Tamio\+3 (1.

| 3 | NUMBER CONCENTRATION,SIZE DISTRIBUTION AND FINE PARTICLE FRACTION OF TROPOSPHERIC AND STRATOSPHERIC AEROSOLS显示文摘Aerosol observations were carried out at Xianghe Scientific Balloon Base (39.45°N, 117°E) using a stratospheric balloon. The particle number concentrations of the tropospheric and stratospheric aerosols were directly explored.The vertical distributions of the number concentration, number-size (that is, particle number versus particle size)distribution, and the fraction of fine particles (0.5 μm>r>0.15 μm/r>0.15 μm) are reported in this paper. The profiles of particle concentration present multi-peak phenomenon. The pattern of size distribution for atmospheric aerosol indicates a tri-modal (r=~0.2 μm, ~0.88 μm and ~7.0 μm) and a bi-modal (r=~0.13 μm and 2.0 μm). The number-size distribution almost fits the Junge distribution for particles with r<0.5 μm in the stratosphere of 1993 and the troposphere of 1994. But the distributions of coarse particles (r>0.5 μm) are not uniform. The number-size distribution exhibits also a wide size range in the troposphere of 1993. The results demonstrate that fine particles represent the major portion in the troposphere during the measurement period, reaching as high as 95% in 1994. Certain coarse particle peaks in the troposphere were attributed to clouds and other causes, and in the stratosphere to volcanic eruption. The stratospheric aerosol layer consists of unique fractions of fine or coarse particles depending on their sources. In summary, the process of gas-to-particles conversion was active and the coarse particles were rich over the Xianghe area. The measurements also demonstrate that the spatial and temporal atmospheric aerosol distributions are nonuniform and changeful. | Li Xu Guangyu Shi Li Zhang Jun Zhou Yasunobu Iwasaka | 2003 | China Particuology2003，1，5： | 1 |

| 5 | 基于静稳天气下气球探空实验的中国沙漠地区沙尘气溶胶的垂直分布(英文)显示文摘塔克拉玛干沙漠是亚洲沙尘气溶胶的重要源地。为探讨塔克拉玛干地区沙尘气溶胶的理化特性与时空变化,研究其环境与气候效应,本文分析了四个季节在中国敦煌(塔克拉玛干沙漠内)取得的探空气球观测数据,包括气溶胶的数浓度、粒径分布、质量浓度及在西风主导下的水平输送通量。气溶胶数浓度的垂直廓线显示,来自沙漠地区的矿物粒子对局地环境与气候有重要影响,且所有季节都存在长距离输送。粒子谱分布显示局地有大量粗粒子输入。结果说明,源于塔克拉玛干沙漠的沙尘气溶胶的背景输送有着重要的科学意义,需进一步研究其对东亚和西太平洋地区环境与气候的影响。 | HABIB Ammara CHEN Bin SHI Guangyu IWASAKA Yasunobu NATH Debashis KHALID Bushra TAN Saichun MAHMOOD Tariq JIAO Reguang NTWALI Didier | 2019 | Atmospheric and Oceanic Science Letters2019，12，1： | 0 |
