Boundary conditions for magnetopause processes such as reconnection can be understood by studying the properties of magnetosheath plasma as it flows toward this transition. This manuscript reviews the role of electromagnetic ion cyclotron instabilities in constraining ion temperature anisotropies in the magnetosheath. Linear Vlasov theory and hybrid computer simulations have demonstrated that the inverse correlation between the proton anisotropy and the parallel proton {beta} observed from AMPTE/CCE in the subsolar sheath is due to wave-particle scattering by ion cyclotron anisotropy instabilities. Recent research on this topic is reviewed and the application of this inverse correlation to a successful bounded anisotropy model of proton temperatures in the sheath is described.
