Retrospect and prospect of ionospheric weather observed by FORMOSAT-3/COSMIC and FORMOSAT-7/COSMIC-2
Terrestrial, Atmospheric and Oceanic Sciences, 2022 Key Points FORMOSAT-3/COSMIC and FORMOSAT-7/COSMIC-2 uniformly observe 3D electron density. FORMOSAT-3 and FORMOSAT-7 enable ionospheric weather forecasting.

Wavenumber-4 Structure in COSMIC-2 Observations: Vertical Plane Perspective
Remote Sensing, 2023 High-rate radio occultation (RO) in COSMIC-2 (FORMOSAT7) enables us to investigate the finer details of the ionosphere owing to the measurements being made at a significantly high spatiotemporal resolution, which was unthinkable a decade ago. In the vertical plane, local-time ionospheric wavenumber-4 (WN4) structures display tilted phase-fronts over ...

Improving topside ionospheric empirical model using FORMOSAT-7/COSMIC-2 data
Journal of Geodesy, 2023 AbstractThe precise description of the topside ionosphere using an ionospheric empirical model has always been a work in progress. The NeQuick topside model is greatly enhanced by adopting radio occultation data from the FORMOSAT-7/COSMIC-2 constellation.

X-ray Emission Processes in Extragalactic Jets, Lobes and Hot Spots [PDF]
, 2003 This paper is a brief review of the processes responsible for X-ray emission from radio jets, lobes and hot spots. Possible photons in inverse Compton scattering models include the radio synchrotron radiation itself (i.e.
