Abstract : Using 3D global Particle-In-Cell (PIC) simulations with the northward interplanetary magnetic field (IMF), we show the Alfven transition layer (ATL) that distinguishes the stagnant exterior cusp (SEC) from the magnetosheath. We show ATL extends from SEC to dayside magnetosheath both duskward and dawnward, asymmetrically. We discuss how ATL characterize the magnetosphere, which is strongly associated with the complicated ion and electron fluxes mainly due to the curvature drifts.
