changes throughout the Earth's geospace due to the fast reduction and recovery
of solar EUV irradiation. It modifies local and global energetics, dynamics,
and the ionospheric ionization supply, leading to substantial changes in the
coupled magnetosphere-ionosphere-thermosphere-mesosphere (geospace) system. It
is an idealized "active experiment" to explore the impulse-response
dynamics of geospace and to address some of the fundamental scientific
questions in geospace. The 21 August 2017 solar eclipse provides an
unprecedented opportunity for this because of the large amount of observational
data obtained during the eclipse with recent major advances in sensitivity,
spatial/temporal resolution, and global coverage of measurements, as well as
the development of sophisticated geospace modeling tools. This special issue
aims at quantifying the new understanding of the solar eclipse effects on
geospace. This new understanding includes, but not limited to, global
ionospheric and thermospheric changes, responses of neutral composition,
temperature, and winds, traveling ionospheric disturbances, geomagnetic and
electric field disturbances, localized and meso-scale structures, lower
ionospheric changes and associated impacts on VLF/LF/HF radio propagation.</span></p>
