چکیده

he Thermosphere, Ionosphere, Mesosphere Energetics and Dynamics (TIMED) mission is a low-cost NASA Sun-Earth Connections mission designed to provide a basic understanding of the least explored and least understood region of the Earth’s environment—the mesosphere, lower thermosphere, and ionosphere (MLTI). The MLTI region is located approximately 60 to 180 km above the surface and is a gateway between the Earth’s lower atmosphere, in which we live, and space. The TIMED suite of four remote sensing instruments measures energy inputs and outputs in the MLTI region as well as its basic structure, including seasonal and latitudinal variations. Over its 2-year mission, TIMED is investigating the relative importance of various radiative, chemical, electrodynamic, and dynamic processes that govern the structure and variability of the MLTI region. This article presents an overview of TIMED mission science and objectives.
