Real-Time Tomographic Inversion of Truncated Ionospheric GNSS Radio Occultations

Remote Sensing, 2023
This paper presents a new way of combining Abel inversion and the Chapman model with a linearly increasing scale height to retrieve ionospheric electron density vertical profiles from truncated-sounding radio-occultation data. A linear Vary–Chap model is

Analysis of the differences between GPS radio occultation and radiosonde atmosphere profiles in Egypt

Egyptian Journal of Remote Sensing and Space Sciences, 2022
Difference values between Global Positioning System (GPS)-Radio Occultation (RO) and radiosonde (RS) profiles are analyzed to assess the integration applicability between them in Egypt.

Estimation and evaluation of COSMIC radio occultation excess phase using undifferenced measurements [PDF]

Atmospheric Measurement Techniques, 2017
In the GPS radio occultation technique, the atmospheric excess phase (AEP) can be used to derive the refractivity, which is an important quantity in numerical weather prediction.

Analysis of Satellite Radio Occultation Architecture and its Stakeholders

, 2021
Global Navigation Satellite System Radio Occultation (GNSS-RO) is a technique that relies on the change of a signal transmitted from a Global Navigation Satellite System (GNSS) as it passes through the planet’s atmosphere.

Generation of a bending angle radio occultation climatology (BAROCLIM) and its use in radio occultation retrievals [PDF]

Atmospheric Measurement Techniques, 2015
In this paper, we introduce a bending angle radio occultation climatology (BAROCLIM) based on Formosat-3/COSMIC (F3C) data. This climatology represents the monthly-mean atmospheric state from 2006 to 2012.

Radio interferometric observation of an asteroid occultation [PDF]

, 2018
The occultation of the radio galaxy 0141+268 by the asteroid (372) Palma on 2017 May 15 was observed using six antennas of the Very Long Baseline Array (VLBA). The shadow of Palma crossed the VLBA station at Brewster, Washington.

Radio occultation profile

, 2021
Figure of electron density profile (and corresponding coordinates of observations) detected with COSMIC satellite measurements using radio-occultation technique. The profile was measured at 10:55 UT, 7 minutes before the earthquake.

Fluctuations of radio occultation signals in sounding the Earth's atmosphere [PDF]

Atmospheric Measurement Techniques, 2018
We discuss the relationships that link the observed fluctuation spectra of the amplitude and phase of signals used for the radio occultation sounding of the Earth's atmosphere, with the spectra of atmospheric inhomogeneities.
