Abstract The plasma sheet boundary layer dynamics during substorms are analyzed using ISEE 1 and 2 energetic particle flux data. Considering the plasma sheet boundary layer as a tangential discontinuity and thus its movements as perpendicular to the local magnetic field direction, the differential timing of the two spacecraft data sets is used to calculate the boundary layer velocity and thickness. The velocity values are deduced to be of the order of 40 km/s and boundary thickness varies from a few tens of km to more than 4 RE with an average value of ∼5000 km. For a majority of the boundaries studied the boundary layer appears simultaneously in all energy channels; within it significant spectral variations are observed and the spectrum is harder at plasma sheet recovery. The experimental data are discussed in the framework of the actual plasma sheet thinning models.
