GNSS Radio Occultation Simulation Using Multiple Phase Screen Orbit Sampling
, 2020 Wave optics propagators (WOPs) are commonlyused to describe the propagation of radio signals through earth’satmosphere. In radio occultation (RO) context, multiple phasescreen (MPS) method has been used to model the effects of theatmosphere in Global ...

Influences of Sudden Stratospheric Warming Events on Tropopause Based on GNSS Radio Occultation Data
Atmosphere, 2023 Sudden Stratospheric Warming (SSW) events have a strong impact on the tropospheric weather and climate. Past researchers have carried out extensive studies investigating the theories of interactions between the stratosphere and the troposphere.

Sensing Heavy Precipitation With GNSS Polarimetric Radio Occultations [PDF]
Geophysical Research Letters, 2019 AbstractThis study presents, for the first time ever, occulting signals of the Global Navigation Satellite Systems (GNSSs) acquired at two polarizations from a Low Earth Orbiter, and it shows that they sense heavy precipitation. The data sets are obtained from early stages of the Radio Occultation and Heavy Precipitation experiment aboard the PAZ ...
