Description
Satellite engineers, operators, and radiation belt researchers share a common desire to understand and predict the structure and variability of Earth's radiation belts. In the radiation belt community, there is a need for improved scientific understanding of the radiation belts, more accurate dynamic and climatological models, space weather restitution and prediction and a mechanism for more efficient transfer of scientific understanding to the space community. To allow for such advancements to take place, IPODE (Ionising Particle Onera DatabasE) has been developed at ONERA under CNES funding in the frame of the CRATERRE project and EU funding (MAARBLE project). This database is composed of nearly an hundred and a half spacecraft/instrument couples for in-situ Earth’s particle measurements (electron, proton and alpha particles fluxes). The energy range covers roughly ~0.1 keV to few MeV for electrons, ~0.1keV to few 100s MeV for protons. A wide range of orbits are covered: geosynchronous (GEO), global positioning systems (GPS), elliptical (HEO) and low altitude (LEO). Measurements have been and are still gathered through open source data or collaborations between ONERA and international institutions such as Los Alamos National Laboratory (LANL), Aerospace Corporation, JAXA (CNES-JAXA agreement), Moscow State University (MSU) and CONAE (CNES-CONAE agreement). The principal strength of this data base is its global spatial and long time coverage. Moreover, these data are largely analysed and filtered to ensure good quality of measurements and therefore allows to perform radiation belt dynamics survey in near real time and in various regions of the Earth’s space.
This data base has already resulted in the development of models such as IGE 2006, MEO V2, MEO at and nearby Galileo Orbit, OZONE the outer zone electron belt specification model, GREEN, and is used for radiation belt data assimilation and Salammbô code validation.
