这项由四颗卫星组成的星团任务研究与太阳风和磁层等离子体相互作用有关的小尺度结构和物理过程。集群活动档案(网址：http://caa.estec.esa.int)将以标准格式包含一整套集群高分辨率数据和其他相关产品，并以机器可读格式包含一整套元数据。压缩格式的数据文件总量预计将超过50TB。数据档案向公众开放，适合全世界科学界的科学使用和出版。CAA旨在为搜索和访问这些数据和辅助产品提供用户友好的服务。CAA于2006年2月开始运作，截至2008年夏季，拥有大多数集群仪器至少在运作的头5年(2001-2005年)的数据。产品的覆盖面和范围正在不断改进，每个航天器提供了200多个数据集，包括高分辨率的磁场和电直流场和波谱；从几个eV到数百keV的完整三维电子和离子分布函数；以及各种辅助和浏览产品，以帮助航天器和事件定位。民航局正在继续扩大和改进该系统的在线能力和现有数据的质量。它将增加2006-2009年的新数据档案，并正在筹备在多国办事处任务完成后建立全面覆盖的长期档案。
The four-satellite Cluster mission investigates the small-scale structures and physical processes related to interaction between the solar wind and the magnetospheric plasma. The Cluster Active Archive (CAA) (URL: http://caa.estec.esa.int ) will contain the entire set of Cluster high-resolution data and other allied products in a standard format and with a complete set of metadata in machine readable format. The total amount of the data files in compressed format is expected to exceed 50 TB. The data archive is publicly accessible and suitable for science use and publication by the world-wide scientific community. The CAA aims to provide user-friendly services for searching and accessing these data and ancillary products. The CAA became operational in February 2006 and as of Summer 2008 has data from most of the Cluster instruments for at least the first 5 years of operations (2001–2005). The coverage and range of products are being continually improved with more than 200 datasets available from each spacecraft, including high-resolution magnetic and electric DC fields and wave spectra; full three-dimensional electron and ion distribution functions from a few eV to hundreds of keV; and various ancillary and browse products to help with spacecraft and event location. The CAA is continuing to extend and improve the online capabilities of the system and the quality of the existing data. It will add new data files for years 2006–2009 and is preparing for the long-term archive with complete coverage after the completion of the Cluster mission.
