ICET

The IGETS data base at GFZ Potsdam http://www.re3data.org/repository/r3d100010300 continues the activities of the International Center for Earth Tides (ICET), in particular, in collecting, archiving and distributing Earth tide records from long series of gravimeters, tiltmeters, strainmeters and other geodynamic sensors. The ICET Data Bank contains results from 360 tidal gravity stations: hourly values, main tidal waves obtained by least squares analyses, residual vectors, oceanic attraction and loading vectors. The Data Bank contains also data from tiltmeters and extensometers. ICET is responsible for the Information System and Data Center of the Global Geodynamic Project (GGP). The tasks ascribed to ICET are : to collect all available measurements of Earth tides (which is its task as World Data Centre C), to evaluate these data by convenient methods of analysis in order to reduce the very large amount of measurements to a limited number of parameters which should contain all the desired and needed geophysical information, to compare the data from different instruments and different stations distributed all over the world, evaluate their precision and accuracy from the point of view of internal errors as well as external errors, to help to solve the basic problem of calibrations and to organize reference stations or build reference calibration devices, to fill gaps in information or data as far as feasible, to build a data bank allowing immediate and easy comparison of Earth tide parameters with different Earth models and other geodetical and geophysical parameters like geographical position, Bouguer anomaly, crustal thickness and age, heat flow, ... to ensure a broad diffusion of the results and information to all interested laboratories and individual scientists.

位于波茨坦 GFZ 的 IGETS 数据库（http://www.re3data.org/repository/r3d100010300）延续着国际地球潮汐中心（ICET）的活动，特别是针对收集、存档和分发来自长期重力计、倾斜仪、应变计以及其他地球动力学传感器的地球潮汐记录。ICET 数据库包含来自 360 个潮汐重力站的成果：每小时数值、通过最小二乘分析获得的主要潮汐波、残余向量、海洋吸引力和负荷向量。数据库还包含倾斜仪和伸缩仪的数据。ICET 负责全球地球动力学项目（GGP）的信息系统和数据中心。ICET 承担的任务包括：收集所有可用的地球潮汐测量数据（作为世界数据中心 C 的任务），通过便捷的分析方法对这些数据进行评估，以便将大量测量数据缩减为包含所有所需和必要地球物理信息的有限参数，比较来自不同仪器和遍布全球不同站点的数据，从内部误差和外部误差的角度评估其精度和准确性，协助解决校准的基本问题，组织参考站点或构建参考校准设备，尽可能填补信息或数据的空白，构建一个数据库，允许即时且便捷地比较地球潮汐参数与不同的地球模型以及其他地理和地球物理参数，如地理位置、布格异常、地壳厚度和年龄、热流等，以确保将结果和信息广泛传播至所有感兴趣的实验室和个人科学家。
