Journal ArticleDOI
Effect of adiabatic deceleration on the focused transport of solar cosmic rays
TL;DR: In this paper, an explicit formula is given for the deceleration of individual particles as a function of the pitch angle, and other first-order effects of the solar wind, including convection, are incorporated into a numerical code for simulating the transport of energetic particles along the interplanetary magnetic field.

TL;DR: In this paper, high-latitude neutron monitors are used to deduce the intensity-time and anisotropy-time pro-les and pitch-angle distributions of energetic protons near Earth during the major solar event on 2000 July 14 (also known as the Bastille Day event).
Journal ArticleDOI
Spectral properties and length scales of two-dimensional magnetic field models
TL;DR: In this paper, the authors discuss the properties of 2D models of magnetic field fluctuations and turbulence and their observable power spectra and present a technique for determining an ultrascale from observations at a single spacecraft.
