Rapid identification of tsunamigenic earthquakes using GNSS ionospheric sounding. [PDF]

Sci Rep, 2020
AbstractThe largest tsunamis are generated by seafloor uplift resulting from rupture of offshore subduction-zone megathrusts. The rupture of the shallowest part of a megathrust often produces unexpected outsize tsunami relative to their seismic magnitude.

Dataset of Quiet Space Weather Periods for Ionospheric Studies

Earth and Space Science
The ionosphere is a dynamic environment regularly affected from above and from below. This study identifies periods within the years 2000–2023 when the impact from above, driven by space weather, was minimal.

A new zenith hydrostatic delay model for real-time retrievals of GNSS-PWV [PDF]

Atmospheric Measurement Techniques, 2021
The quality of the zenith hydrostatic delay (ZHD) could significantly affect the accuracy of the zenith wet delay (ZWD) of the Global Navigation Satellite System (GNSS) signal, and from the ZWD precipitable water vapor (PWV) can be obtained.
