My current graduate research at the Center of Atmospheric and Space Sciences (CASS)
is focused on Ionosphere F region climatology and thermosphere-ionosphere coupling. The
radio occultation data from six FORMOSAT-3/COSMIC satellites and Global Assimilation of
Ionospheric Measurements Model (GAIM) developed at Utah State University provide
excellent opportunity for understanding various Ionospheric phenomena at mid- and
low-latitudes. Ability to estimate different physical drivers (thermospheric neutral
winds, composition and ExB drifts) through the comprehensive modeling of the global
ionosphere under the different conditions enables to address many current challenges of
the Ionospheric physics.
