This paper presents refined MSFM particle fluxes calculated using DMSP and WIND measurements for the period October 18 - 20, 1995. This particular time period includes the interaction of an intense magnetic cloud with the magnetosphere and is notable because, during the first day, the maximum magnetospheric convection is not concurrent with the maximum magnetospheric compression. Conveniently for comparison, simultaneous compression and convection enhancement occurs later in this campaign period. To achieve increased model accuracy relative to the previously reported run, this run uses DMSP measurements of the auroral zone midnight equatorial boundary, WIND measurements of solar wind density and velocity, and a WIND-based estimate of the cross-polar-cap potential drop. Model fluxes for electrons, protons, and oxygen ions of various keV-magnitude energies are shown in animation.
