    AnotaceSolar variability drives, among other physical processes, the growth of lowfrequency
    electromagnetic waves in the terrestrial magnetosphere. The resulting
    wave-particle interactions in the inner magnetosphere play a critical role in
    radiation belt dynamics. The MAARBLE (Monitoring, Analyzing and Assessing
    Radiation Belt Loss and Energization) project, which was implemented with support
    26 from the European Community's Seventh Framework Programme, investigated in
    detail the properties of these waves and the particular the ways in which these
    waves may influence the energization and loss of radiation belt electrons. The
    MAARBLE project employed multi-spacecraft monitoring of the geospace
    environment, complemented by ground-based monitoring, in order to analyze and
    assess the physical mechanisms leading to radiation belt particle energisation and
    loss. MAARBLE created a database based on measurements from the Cluster,
    THEMIS and CHAMP missions and from the CARISMA and IMAGE ground
    magnetometer networks and containing properties of ULF and VLF waves. The
    database is available to the scientific community through the Cluster Science
    Archive as auxiliary content. Based on the wave database, statistical models of the
    wave activity dependent on the level of geomagnetic activity, solar wind forcing, and
    magnetospheric region have also been developed. Multi-spacecraft particle
    measurements have been incorporated into data assimilation tools, leading to a
    more accurate estimate of the state of the radiation belts. The synergy of wave and
    particle observations at the core of MAARBLE research studies of radiation belt
    dynamics enabled significant advances in understanding the nature of the physical
    processes responsible. In particular new understanding of the nature of ULF
    interactions, both coherent and diffusive, and better representations of multiple
    plasma wave-particle interactions lead to improved coupled models.
