[HTML][HTML] Double-thin-shell approach to deriving total electron content from GNSS signals and implications for ionospheric dynamics near the magnetic equator
T Maruyama, K Hozumi, G Ma, P Supnithi… - Earth, Planets and …, 2021 - Springer
A new technique was developed to estimate the ionospheric total electron content (TEC)
from Global Navigation Satellite System (GNSS) satellite signals. The vertically distributed
electron density was parameterized by two thin-shell layers (double-shell approach). The
spatiotemporal variation of TEC (strictly speaking, partial electron content) associated with
each shell was approximated by the functional fitting of spherical surface harmonics. The
major improvements over the conventional single-shell approach were as follows:(1) the …
