摘要

三十多年来,卫星测高为监测和分析海洋及内陆水域表面提供了宝贵的测量数据。自 1992 年以来,一直至少有两个任务同时提供连续测量数据,从 1990 年代初的 TOPEX/Poseidon 和 ERS-1 开始,到今天大约有 10 颗卫星在工作,包括 ICESat-2、Sentinel-6A 和 SWOT。大多数飞行任务数据都是免费提供的,但格式不同,处理水平不同,参照物(如椭球面或时间)也不同,因此难以进行通用的多任务应用。此外,推导出随时可用的高质量科学产品需要专业知识,而这并不是每个用户都愿意掌握的。多年来,DGFI-TUM 开发并维护了一个开放式高度计数据库(OpenADB),以实现一致的数据管理和组合。该数据库由内部多版本测高(MVA)数据储存库和 OpenADB 门户网站组成。OpenADB 提供方便用户的访问途径,以获取海面高度和海洋潮汐等沿轨衍生产品。它还提供有关卫星测高任务、其观测配置和数据库所提供数据的一般信息。所有产品均可在注册后在 OpenADB 门户网站(https://openadb.dgfi.tum.de)上免费获取。

OpenADB: DGFI-TUM's Open Altimeter Database

For more than three decades, satellite altimetry has provided valuable measurement data for the monitoring and analysis of ocean and inland water surfaces. Since 1992, there have always been at least two simultaneous missions providing continuous measurement data, starting with TOPEX/Poseidon and ERS-1 in the early 1990s and continuing with about 10 satellites active today, including ICESat-2, Sentinel-6A and SWOT. Most mission data are freely available, but in different formats, processing levels and with respect to different references (e.g. ellipsoid or time), making common multi-mission applications difficult. In addition, the derivation of ready-to-use and high-quality scientific products requires expertise that not every user is willing to acquire. Over the years, DGFI-TUM has developed and maintained an Open Altimeter Database (OpenADB) that allows consistent data management and combination. It consists of the internal Multi-Version Altimetry (MVA) data repository and the OpenADB web portal. OpenADB provides user-friendly access to derived along-track products, such as sea surface heights and ocean tides. It also provides general information about the satellite altimetry missions, their observing configurations and about the data provided in the database. All products are freely available on the OpenADB web portal (https://openadb.dgfi.tum.de) after registration.

期刊介绍: Geoscience Data Journal provides an Open Access platform where scientific data can be formally published, in a way that includes scientific peer-review. Thus the dataset creator attains full credit for their efforts, while also improving the scientific record, providing version control for the community and allowing major datasets to be fully described, cited and discovered. An online-only journal, GDJ publishes short data papers cross-linked to – and citing – datasets that have been deposited in approved data centres and awarded DOIs. The journal will also accept articles on data services, and articles which support and inform data publishing best practices. Data is at the heart of science and scientific endeavour. The curation of data and the science associated with it is as important as ever in our understanding of the changing earth system and thereby enabling us to make future predictions. Geoscience Data Journal is working with recognised Data Centres across the globe to develop the future strategy for data publication, the recognition of the value of data and the communication and exploitation of data to the wider science and stakeholder communities.
