摘要。2010年4月，位于冰岛南部边缘的Eyjafjallajokull火山喷发，由全球大气监测站（GAW）在德国Zugspitze/Hohenpeissenberg通过现场测量、臭氧探空仪和ceilometers探测到。来自德国气象局（DWD） ceilometer网络（Flentje et al., 2010）的信息有助于确定气团的来源。我们讨论了二氧化硫（SO2）、硫酸（H2SO4）和颗粒物的地面原位测量，以及臭氧探空仪剖面和用布鲁尔光谱仪进行的二氧化硫柱测量。在Hohenpeissenberg，在此期间还测量了许多活性气体，例如一氧化碳和氮氧化物，以及颗粒性质，例如尺寸分布和离子组成。我们的研究结果描述了2010年4月16日和17日火山柱到达Zugspitze和Hohenpeissenberg，并在此后的数天内停留在行星边界层（PBL）。在大约6-7公里高的霍恩佩森堡，通过云层测量仪的后向散射剖面首次发现了火山灰羽流。在4月17日中午进入PBL后，到4月21日为止，Zugspitze/Hohenpeissenberg的二氧化硫、硫酸和超微米粒子数浓度大幅度增加。
Abstract. Volcanic emissions from the Eyjafjallajokull volcano eruption on the Southern fringe of Iceland in April 2010 were detected at the Global Atmosphere Watch (GAW) station Zugspitze/Hohenpeissenberg (Germany) by means of in-situ measurements, ozone sondes and ceilometers. Information from the German Meteorological Service (DWD) ceilometer network (Flentje et al., 2010) aided identifying the air mass origin. We discuss ground level in-situ measurements of sulphur dioxide (SO2), sulphuric acid (H2SO4) and particulate matter as well as ozone sonde profiles and column measurements of SO2 by a Brewer spectrometer. At Hohenpeissenberg, a number of reactive gases, e.g. carbon monoxide and nitrogen oxides, and particle properties, e.g. size distribution and ionic composition, were additionally measured during this period. Our results describe the arrival of the volcanic plume at Zugspitze and Hohenpeissenberg during 16 and 17 April 2010 and its residence in the planetary boundary layer (PBL) for several days thereafter. The ash plume was first seen in the ceilometer backscatter profiles at Hohenpeissenberg in about 6–7 km altitude. After entrainment into the PBL at noon of 17 April, largely enhanced values of sulphur dioxide, sulphuric acid and super-micron-particle number concentration were recorded at Zugspitze/Hohenpeissenberg till 21 April.
