Description
The Monitoring, Analyzing and Assessing Radiation Belt Loss and Energization (MAARBLE) project has two focussed and synergistic aims: to advance scientific research on radiation belt dynamics; and to enhance data exploitation of European space missions through the combined use of European and US spacecraft measurements and ground-based observations.
MAARBLE employs 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 energization and loss. Particular attention is paid to the role of ULF/VLF waves. A database containing properties of the waves is being created and will be made available to the scientific community. Based on the wave database, a statistical model of the wave activity dependent on the level of geomagnetic activity, solar wind forcing, and magnetospheric region will be developed.
Multi-spacecraft particle measurements are incorporated into data assimilation tools, leading to new understanding of the causal relationships between ULF/VLF waves and radiation belt dynamics. Data assimilation techniques have been proven as a valuable tool in the field of radiation belts, able to guide 'the best' estimate of the state of a complex system.
This talk presents an overview of project results obtained so far. Other papers of this workshop will present selected results in detail.
The MAARBLE collaborative research project has received funding from the European Union under the Seventh Framework Programme (FP7-Space) under grant agreement n 284520.
