Global DAS Month 2023, Teleseismic Event Recordings, Potsdam Fiber

The here referenced dataset provides event-based Distributed Acoustic Sensing (DAS) recordings made with an approximately 22 km long dark telecommunication fiber lying in urban Potsdam and surroundings. For each of 164 M>=5 earthquakes occurring in February 2023 and listed by the USGS, one hour of data is provided starting with the event's origin time. Additionally, the whole day of February 14 is provided in hourly files. The data was recorded in the frame of the global DAS month, an initiative to collaboratively record and share simultaneously recorded DAS data from all over the world (https://www.norsar.no/in-focus/global-das-monitoring-month-february-2023). DAS is an emerging technology increasingly used by seismologists to convert kilometer long optical fibers into seismic sensors.本次引用的数据集包含基于事件的分布式声学传感（Distributed Acoustic Sensing，DAS）记录数据，所用设备为铺设于德国波茨坦市区及周边区域、总长约22公里的暗敷通信光纤。针对美国地质调查局（USGS）收录的2023年2月发生的164场震级M≥5的地震，每份数据均以地震发震时刻为起始点，提供时长1小时的观测记录。此外，数据集还包含2023年2月14日一整日的逐小时分块数据文件。 该数据采集于"全球DAS监测月"项目框架之下，该项目旨在协同采集并共享来自全球各地的同步DAS观测数据（项目详情链接：https://www.norsar.no/in-focus/global-das-monitoring-month-february-2023）。分布式声学传感（DAS）是一项新兴技术，正日益被地震学家用于将长距离光纤转换为地震观测传感器。
