An evaluation of GNSS radio occultation atmospheric profiles from Sentinel-6

Egyptian Journal of Remote Sensing and Space Sciences, 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 (

Principles of variational assimilation of GNSS radio occultation data [PDF]

, 2003
The standard processing of the Global Navigation Satellite System (GNSS) based refractometric data performed by means of a space-borne GPS-receiver was based on the approximate derivation of the local vertical profiles of the atmospheric refractivity by means of the Abel transform.

Probability of intense precipitation from polarimetric GNSS radio occultation observations. [PDF]

Q J R Meteorol Soc, 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 ...

The power of vertical geolocation of atmospheric profiles from GNSS radio occultation. [PDF]

J Geophys Res Atmos, 2017
AbstractHigh‐resolution measurements from Global Navigation Satellite System (GNSS) radio occultation (RO) provide atmospheric profiles with independent information on altitude and pressure. This unique property is of crucial advantage when analyzing atmospheric characteristics that require joint knowledge of altitude and pressure or other ...
