本研究涵盖了在西伯利亚高塔Zotino Tall Tower（ZOTTO）（60.8°N; 89.35°E）测量的超过5年，相当于超过40000小时的颗粒和气体数据。沿着沿着10维轨迹外推，ZOTTO的测量覆盖了欧亚大陆的大部分地区。映射外推ZOTTO数据点的主要人为源区域和西伯利亚火灾地区，符合CO和植被火灾的排放数据。中东中纬度地区的排放源非常突出，有时可能从ZOTTO中看到来自中国北方的排放。测得的光散射和吸收特性的地图支持不同来源类型的解释。发现了三个基本上不同的亚微米颗粒尺寸分布的集群，其中的地图也可以与主要的气溶胶源区。
The present study covers more than 5 yr corresponding to more than 40 000 hours of particle and gas data measured at the Siberian tall tower Zotino Tall Tower (ZOTTO) (60.8°N; 89.35°E). Extrapolated along 10-d back trajectories, the ZOTTO measurements cover large parts of the Eurasian land mass. Mapping the extrapolated ZOTTO data points to major anthropogenic source regions and Siberian fire regions, consistent with emission data for CO and vegetation fires. Middle East mid-latitude sources stand out strongly and possibly emissions from Northern China may be seen at times from ZOTTO. The maps of measured light scattering and absorption characteristics support the interpretation of different source types. Three clusters of substantially different submicrometer particle size distributions were found, the maps of which also could be related to major aerosol source regions.
