Canadian Astronomy Data Centre

The Canadian Astronomy Data Centre (CADC) was established in 1986 by the National Research Council of Canada (NRC), through a grant provided by the Canadian Space Agency (CSA). Over the past 30 years the CADC has evolved from an archiving centre---hosting data from Hubble Space Telescope, Canada-France-Hawaii Telescope, the Gemini observatories, and the James Clerk Maxwell Telescope---into a Science Platform for data-intensive astronomy. The CADC, in partnership with Shared Services Canada, Compute Canada, CANARIE and the university community (funded through the Canadian Foundation for Innovation), offers cloud computing, user-managed storage, group management, and data publication services, in addition to its ongoing mission to provide permanent storage for major data collections. Located at NRC Herzberg Astronomy and Astrophysics Research Centre in Victoria, BC, the CADC staff consists of professional astronomers, software developers, and operations staff who work with the community to develop and deliver leading-edge services to advance Canadian research. The CADC plays a leading role in international efforts to improve the scientific/technical landscape that supports data intensive science. This includes leadership roles in the International Virtual Observatory Alliance and participation in organizations like the Research Data Alliance, CODATA, and the World Data Systems. CADC also contributes significantly to future Canadian projects like the Square Kilometre Array and TMT. In 2019, the Canadian Astronomy Data Centre (CADC) delivered over 2 Petabytes of data (over 200 million individual files) to thousands of astronomers in Canada and in over 80 other countries. The cloud processing system completed over 6 million jobs (over 1100 core years) in 2019.

加拿大天文学数据中心（CADC）成立于1986年，由加拿大国家研究委员会（NRC）建立，得益于加拿大航天局（CSA）的资助。在过去的三十年间，CADC已从一家仅提供数据存档的中心（包括哈勃太空望远镜、加拿大-法国-夏威夷望远镜、双子星座天文台以及詹姆斯·克拉克·麦克斯韦望远镜的数据）演变为一个数据密集型天文学的科学平台。CADC与共享服务加拿大、Compute Canada、CANARIE以及大学社区（由加拿大创新基金会资助）合作，提供云计算、用户管理存储、群组管理以及数据发布服务，同时继续承担为其主要数据集提供永久存储的使命。位于不列颠哥伦比亚省维多利亚市的NRC赫茨伯格天体物理研究中心，CADC的员工包括专业天文学家、软件开发人员和运维人员，他们与社区合作，开发和提供尖端服务，以推进加拿大研究。CADC在国际努力中发挥着主导作用，旨在改善支持数据密集型科学的研究/技术环境，这包括在国际虚拟天文台联盟（IVOA）中的领导角色，以及参与研究数据联盟（RDA）、CODATA和世界数据系统等组织。CADC还对加拿大的未来项目，如平方公里阵列（SKA）和TMT望远镜项目做出了重大贡献。2019年，加拿大天文学数据中心（CADC）向加拿大及全球80多个国家的数千名天文学家交付了超过2百万兆字节的数据（超过2亿个单独文件），云处理系统在2019年完成了超过600万项任务（超过1100个核心年）。
