摘要
GEOSCOPE天文台(巴黎地球物理研究所[IPGP]和École et Observatoire des Sciences de la Terre de Strasbourg, 1982年)为科学界提供了40多年的高质量连续宽带数据。1982年开始时只有两个电台,由于众多的国际合作伙伴关系,该网络多年来不断发展壮大。目前,34个台站在各大洲的18个国家和各大洋的岛屿上开展业务,填补了全球地球覆盖的重要空白。大多数第一批安装的站点今天仍在运行,可以进行长期观测,并且正在寻找新的站点以进一步改善全球覆盖范围。多年来,GEOSCOPE为定义当今的全球地震学标准(数据格式,数据质量水平,仪器要求)做出了贡献,这是法国对全球地震观测国际努力的贡献。这些台站配备了最优质的地震仪(从80年代初的第一个STS-1到今天的最后一个STS-6A和Trillium T360)和数字化仪(Q330HR和Centaur),以高保真度记录所有类型震源产生的地面运动。实时数据被发送到海啸预警中心,IPGP、Epos-France和Earthscope数据中心都可以获得验证数据和实时数据。GEOSCOPE数据和元数据的质量通过每日和每年的验证得到保证,从而能够发现和缓解问题。GEOSCOPE与其他全球网络合作,在研究地球结构和全球动力学以及所有类型震源的特征方面已经并将继续发挥关键作用。
GEOSCOPE Network: 40 Yr of Global Broadband Seismic Data
The GEOSCOPE observatory (Institut de physique du globe de Paris [IPGP] and École et Observatoire des Sciences de la Terre de Strasbourg, 1982) provides more than four decades of high-quality continuous broadband data to the scientific community. Started in 1982 with only two stations, the network has grown over the years thanks to numerous international partnerships. At present, 34 stations operate in 18 countries across all continents and on islands throughout the oceans, filling important gaps in global Earth coverage. Most of the first installed stations are still running today, allowing for long-term observations, and new sites are being prospected to further improve global coverage. Over the years, GEOSCOPE has contributed to defining today’s global seismology standards (data format, data quality level, instrumentation requirements), being the French contribution to the international effort for global seismic observations. The stations are instrumented with the best quality seismometers (from the very first STS-1 in the early 80s to the last STS-6A and Trillium T360 today) and digitizers (Q330HR and Centaur) to record with high fidelity the ground motions generated by all types of seismic sources. Real-time data are sent to the tsunami warning centers and both validated and real-time data are available at the IPGP, Epos-France and Earthscope data centers. The quality of GEOSCOPE data and metadata is ensured by daily and yearly validation that enables issue detection and mitigation. GEOSCOPE, in collaboration with the other global networks, has played and continues to play a crucial role in the study of Earth’s structure and global dynamics and the characterization of all types of seismic sources.
