Coordinates for Representing Radiation Belt Particle Flux

Fifty years have passed since the parameter \textquotedblleftL-star\textquotedblright was introduced in geomagnetically trapped particle dynamics. It is thus timely to review the use of adiabatic theory in present-day studies of the radiation belts, with the intention of helping to prevent common misinterpretations and the frequent confusion between concepts like \textquotedblleftdistance to the equatorial point of a field line,\textquotedblright McIlwain\textquoterights L-value, and the trapped particle\textquoterights adia ...

The \textquotedblleftzebra stripes\textquotedblright: An effect of F-region zonal plasma drifts on the longitudinal distribution of radiation belt particles

We examine a characteristic effect, namely, the ubiquitous appearance of structured peaks and valleys called zebra stripes in the spectrograms of energetic electrons and ions trapped in the inner belt below L ~ 3. We propose an explanation of this phenomenon as a purely kinematic consequence of particle drift velocity modulation caused by F region zonal plasma drifts in the ionosphere. In other words, we amend the traditional assumption that the electric field associated with ionospheric plasma drives trapped particle distri ...
