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

Optical and Radio Occultation Analysis [PDF]
Highlights of Astronomy, 1971 The study of occultations of radio sources by the Moon has proved a powerful method of studying the structure of radio sources with a resolution limit, in some cases, as small as 0″.1 and at the same time of obtaining positions of the radio components with an accuracy of the order of 0″.1 to 1″.

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.

Advanced Functional Materials, Volume 36, Issue 43, 29 May 2026.A novel phthalocyanine (PC)‐based metal–organic framework (MOFs) is synthesized using ditopic PC linkers obtained through regioselective statistical condensation. The resulting MOF exhibits significant improvements in electronic absorption, thereby enhancing the material's performance in light harvesting and energy conversion.

Radio Occultation Exploration of Mars [PDF]
Symposium - International Astronomical Union, 1974 The radio occultation technique, consisting of the observation of changes in the phase, frequency, and amplitude of a radio signal from a spacecraft as it passes through the atmosphere of a planet before and after occultation, was first applied to measure the atmosphere of Mars with the Mariner IV spacecraft in 1965. The interpretation of these changes
