Assessment of ZTD Derived from COSMIC Occultation Data with ECWMF, Radiosondes, and GNSS [PDF]
Sensors, 2022 Global Navigation Satellite System (GNSS) signals generate slant tropospheric delays when they pass through the atmosphere, which is recognized as the main source of error in many spatial geodetic applications. The zenith tropospheric delay (ZTD) derived

Probability of intense precipitation from polarimetric GNSS radio occultation observations [PDF]
Quarterly Journal of the Royal Meteorological Society, 2018 There is currently a gap in satellite observations of the moisture structure during heavy precipitation conditions, since infrared and microwave sounders cannot sense water‐vapour structure near the surface in the presence of intense precipitation. Conversely, Global Navigation Satellite System (GNSS) radio occultations (RO) can profile the moisture ...

An evaluation of GNSS radio occultation atmospheric profiles from Sentinel-6
Egyptian Journal of Remote Sensing and Space Science, 2023 The Global Navigation Satellite System (GNSS) radio occultation (RO) significantly impacts climate change monitoring. GNSS RO is based mainly on the refraction of the GNSS signals transmitted by satellites and received by a receiver on a Low Earth Orbit (
