对于地面宇宙射线观测站来说，大气层是探测器的一个组成部分。空气荧光探测器（FD）对大气中的气溶胶特别敏感。这些气溶胶主要由云和尘埃组成，可以强烈影响宇宙射线引起的大范围空气簇射的荧光和切伦科夫光的传播。皮埃尔·俄歇天文台有一个全面的计划来监测探测器大气体积内的气溶胶。本文将讨论影响FD重建的气溶胶参数。沿着简要介绍皮埃尔俄歇天文台部署的气溶胶监测系统以及这些系统的一些测量结果。
For a ground based cosmic-ray observatory the atmosphere is an integral part of the detector. Air fluorescence detectors (FDs) are particularly sensitive to the presence of aerosols in the atmosphere. These aerosols, consisting mainly of clouds and dust, can strongly affect the propagation of fluorescence and Cherenkov light from cosmic-ray induced extensive air showers. The Pierre Auger Observatory has a comprehensive program to monitor the aerosols within the atmospheric volume of the detector. In this paper the aerosol parameters that affect FD reconstruction will be discussed. The aerosol monitoring systems that have been deployed at the Pierre Auger Observatory will be briefly described along with some measurements from these systems.
