Variations of Kelvin Waves around the Tropical Tropopause Inversion Layer from GNSS RO Measurements
Journal of the Atmospheric SciencesAbstract In the present study, the tropical tropopause inversion layer (TIL) Kelvin waves are extracted from the Global Navigation Satellite System (GNSS) radio occultation (RO) temperature data of multiple missions from January 2007 to December 2020.

Data Assimilation Impact of GNSS RO Measurements from Cube Satellites on Arctic Weather Forecasts
Monthly Weather ReviewAbstract In this study, the effects of assimilating Global Navigation Satellite System (GNSS) radio occultation (RO) observations from existing and recently added commercial cube satellites on analyses and forecasts over the Arctic region were investigated by conducting observing system experiments (OSEs). Profiles of refractivity were assimilated with

Comparison of reference upper-air GRUAN and homogenized RHARM data with GNSS-RO
The study of thermodynamical variables, such as temperature and relative humidity in the upper troposphere/lower stratosphere (UT/LS), is one of the key elements for the study of climate change. Several studies estimated trends both regionally and globally in the UT/LS, using both satellite and ground-based data and different measurement techniques ...Fabrizio Marra +5 more

GPS Single-Frequency: From First cm-POD to Single Frequency GNSS-RO/R
2018In this section we introduce what we call “Positive Code-Phase” linear combination or the LP linear combination (phase and code added) to eliminate the first-order ionosphere effect and estimate LEO orbits using single-frequency GPS measurements, (see Svehla and Rothacher 2003a; 2005b).
