The CHAMP (CHAllenging Minisatellite Payload) satellite was a highly successful German Low Earth Orbit (LEO) mission that operated for more than ten years (2001 – 2010), providing high precision gravity and magnetic field measurements. Due to its almost circular and near-polar orbit it was able to achieve homogeneous and complete global coverage of the Earth's sphere, with orbit and...

ULF waves with frequencies of a few millihertz have been associated with changes in the flux levels among relativistic electrons comprising the outer zone of the radiation belts. In particular, the fluxes of electrons with energies > 1 MeV in the outer radiation belt increase and decrease during geospace magnetic storms. For all storms studied by Reeves et al. [2003], only about half of them...

In studies of particles' radial diffusion processes in the magnetosphere it is well known that Ultra-Low Frequency (ULF) waves of frequency m*ω_d can resonantly interact with particles of drift frequency ω_d, where m is the azimuthal mode number of the waves; however due to difficulties in estimating m an over-simplifying assumption is often made in radial diffusion simulations, namely that...

The instrument ELMAVAN is being prepared at the Institute of Atmospheric Physics, Prague for the Russian Resonance project with international participation, currently scheduled to be launched in 2015. The aim of this four-spacecraft mission is to investigate properties of wave-particle interactions and plasma dynamics in the inner magnetosphere of the Earth with the focus on phenomena...

Specification Models of the Radiation Belts: Radiation Environment Data Analyses/Validation
Poster
The Open Data Interface (ODI) is a database system for storing space environment data and metadata using an SQL server. The system is compliant with the SPASE data model. Data can be ingested from text files and CDF/ISTP/PRBEM files. Currently there are more than 100 datasets in the database such as IMP8/GME, SREM, XMM/ERMD, GOES particle and radiation data, and indices such as Dst, Kp, and...

Like in any data sets, wave intensity measurements are often affected by background issues. Due to the properties of chorus emissions, it is expected to have a stronger impact on lower and upper chorus band than on plasmasheric hiss or lightning whistlers emissions. In this study we have analysed background level for each wave band available in the ONERA database (DE1/PWI, CRRES/PWE,...

The flux of relativistic electrons in the Earth's radiation belts is highly variable and can change by orders of magnitude on timescales of a few hours. Understanding the drivers for these changes is important as energetic electrons can damage satellites. Forecasting the high-energy electron flux in the radiation belts is a challenge that has been taken on by the FP7 project SPACECAST. The BAS...

Following the launch by NASA of the Radiation Belt Storm Probes (RBSP) twin spacecraft, now named the Van Allen Probes, the discovery of a storage ring was announced: Baker et al., Science, 2013. This transient feature was observed during September 2012, following the arrival of an interplanetary shock, was located between L=3.0 and L=3.5 and consisted of about 4 to 6 MeV electrons. During...

The radiation belt electron precipitation (RBEP) into the topside ionosphere is a phenomenon which is known for several decades. However, the radiation belt source and loss mechanisms have not still well understood, including PBEP. Here we present the results of a systematic study of RBEP observations, as obtained from the satellite DEMETER (Detection of Electromagnetic Emissions Transmitted...

The MAARBLE (Monitoring, Analyzing and Assessing Radiation Belt Loss and Energization) project has two focused and synergistic aims: to advance scientific research on radiation belt dynamics; and to enhance data exploitation of European space missions through combined use of European and US spacecraft measurements and ground-based observations. As a part of the project we create an extended...

Focused on the exceptional 2003 Halloween geospace magnetic storm, when Dst reached a minimum of -383 nT, we examine data from topside ionosphere and two magnetospheric missions (CHAMP, Cluster, and Geotail) for signatures of ULF waves. We present the overall ULF wave activity through the six-day interval from 27 October to 1 November 2003 as observed by the three spacecraft and by the Andenes...
