Cluster3

The ESA Cluster mission is a key European resource for high-quality in-situ data on plasma conditions in the magnetosphere, composed of 4 identical satellites with 11 instruments onboard each spacecraft. The separation distance between the spacecraft is adjusted depending on the regions of interest crossed by the tetrahedron and on the spatial scales of the structures to be studied; it varies from ten kilometres to a few Earth radii. In particular, the satellites cross the plasmasphere every 50 hours at different altitudes, latitudes and MLT sectors. These data are openly available via ESA's Cluster Science Archive (CSA, http://www.cosmos.esa.int/web/csa), which is located at ESAC, Madrid, Spain.
