AB: Our geospace environment is controlled by the parameters of the solar wind. A significant progress in modeling of the magnetosphere has been achieved recently and simulations of its response to specific interplanetary events becomes possible. An important question of the primary importance to the space weather research and forecasting is whether a spacecraft orbiting around the L1 point samples the same solar wind that hits the Earth. We use a high-resolution numerical magnetohydrodynamic model driven by near-Earth spacecraft observations. Selected events are used to investigate the evolution of small-scale solar wind structures and evaluate limitations of current observational capabilities when combined with available numerical models.
