先进的LIGO探测器对引力波的灵敏度可能会受到探测器本身外部环境干扰的影响。自从从最初的LIGO阶段过渡以来，用于调查这些环境影响的设备和技术已经取得了许多改进。这些方法有助于在先进探测器时代的前三次观测运行中追踪和减轻噪声源，使环境噪声的环境贡献低于探测器的背景噪声水平。在本文中，我们描述了所使用的方法，以及它们如何导致噪音源的缓解，环境监测在验证引力波事件中所发挥的作用，以及未来观测运行的计划。
The sensitivity of the advanced LIGO detectors to gravitational waves can be affected by environmental disturbances external to the detectors themselves. Since the transition from the former initial LIGO phase, many improvements have been made to the equipment and techniques used to investigate these environmental effects. These methods have aided in tracking down and mitigating noise sources throughout the first three observing runs of the advanced detector era, keeping the ambient contribution of environmental noise below the background noise levels of the detectors. In this paper we describe the methods used and how they have led to the mitigation of noise sources, the role that environmental monitoring has played in the validation of gravitational wave events, and plans for future observing runs.
