项目摘要

The data volumes in observational and computational seismology are rapidly expanding. This is due in part to ever increasing continuous data of global, regional, and local permanent station density, large scale experiments, and last not least, the increasingly important options to generate highly valuable simulation data that should be stored with the same priority than observations. Furthermore, seismology is going beyond data reduction (e.g., by extracting travel times or surface wave phase velocities) towards complete waveform processing and simulation. It is commonly accepted in the seismological community that the suite of database and processing tools that was developed in the past decade is now outdated and requires novel approaches. In this pilot project we intend to develop a new paradigm with the intention to closely link data archiving, waveform processing, and simulation infrastructure with strong emphasis on the field of seismology. These developments shall be carried out in close collaboration with major ongoing international projects in seismology (NERIES, SPICE, CIG, SCEC) as well as national initiatives (e.g., webDC, GFZ Potsdam) and data centers (BGR/SZGRF, ORFEUS, IRIS). While the focus of those projects lies in the handling of real-time observations, automatic processing of large data sets and/or the provision of computational wave propagation algorithms, the main complementary developments envisaged in this project are (1) an open source, modular, multi-component data base with access to observational infrastructure (partly provided by NERIES); (2) a link between data base, multicomponent processing tools and executable simulation algorithms (provided by SPICE); and (3) the development of formats and standards to combine the joint storage and processing of observations and simulations (partly provided by FDNS and IRIS). All developments will be developed in close collaboration with and be freely available to the relevant user communities.

观测和计算地震学的数据量正在迅速扩大。这部分是由于不断增加的全球，区域和本地永久站密度的连续数据，大规模的实验，最后同样重要的是，越来越重要的选项，以生成非常有价值的模拟数据，应该以与观测相同的优先级存储。此外，地震学正在超越数据简化（例如，通过提取传播时间或表面波相速度）来完成波形处理和仿真。地震学界普遍认为，过去十年开发的数据库和处理工具套件现已过时，需要新的方法。在这个试点项目中，我们打算开发一个新的范例，旨在紧密联系数据归档，波形处理和模拟基础设施，重点放在地震学领域。这些开发应与正在进行的地震学主要国际项目（NERIES、SPICE、CIG、SCEC）以及国家倡议（例如，webDC、GFZ波茨坦）和数据中心（BGR/SZGRF、ORFEUS、IRIS）。虽然这些项目的重点在于处理实时观测、自动处理大型数据集和/或提供计算波传播算法，但本项目设想的主要补充发展是：（1）开放源码、模块化、多组成部分数据库，可利用观测基础设施（部分由NERIES提供）;（2）数据库、多部件处理工具和可执行仿真算法之间的链接（由SPICE提供）;以及（3）开发格式和标准，以联合收割机观测和模拟的联合存储和处理（部分由FDNS和IRIS提供）。所有开发都将与相关用户社区密切合作开发，并免费提供给相关用户社区。
