Abstract The Radiation Belt Storm Probes (RBSP)-Energetic Particle, Composition, and
Thermal Plasma (ECT) suite contains an innovative complement of particle instruments to …

Thirty years ago Paulikas and Blake (1979) showed a remarkable correlation between
geosynchronous relativistic electron fluxes and solar wind speed (Vsw). This seminal result …

Recently published data from Reeves et al.(2011) on the fluxes of 1.8–3.5 MeV electrons at
geostationary orbit are subjected to Error Reduction Ratio (ERR) analysis in order to identify …

The methodology based on the Error Reduction Ratio (ERR) determines the causal
relationship between the input and output for a wide class of nonlinear systems. In the …

Observational data sets in space physics often contain instrumental and sampling errors, as
well as large gaps. This is both an obstacle and an incentive for research, since continuous …

We present the first direct observations of equatorial electron phase space density (PSD) as
a function of the three adiabatic invariants throughout the outer radiation belt using data from …

The dependence of outer‐radiation belt electron fluxes upon solar wind velocity and density
is investigated using the OMNI solar wind database and LANL‐GEO geosynchronous …

Space science deals with the bodies within the solar system and the interplanetary medium;
the primary focus is on atmospheres and above-at Earth the short timescale variation in the …

Radiation belt behavior is often analyzed in terms of adiabatic invariants, of which the third
roughly characterizes the radial distance of particle drift shells. The outermost, or last closed …

Severe space weather produced by disturbed conditions on the Sun results in harmful
effects both for humans in space and in high‐latitude flights, and for technological systems …
