Vertical Atmospheric Structures Associated with Positive Biases in COSMIC-2 Refractivity Retrievals
Journal of Atmospheric and Oceanic Technology, 2022Abstract Representation of complex vertical structures observed in the troposphere can vary depending on data sources. The radio occultation (RO) technique offers great advantages for sensing the atmosphere down to its lowermost layers using high-resolution measurements collected by satellites on low-Earth orbit (LEO).

Characteristics of ionospheric wavenumber structures in COSMIC-2 RO observations
2023High-rate radio occultation (RO) in COSMIC2 (FORMOSAT7) enables us to investigate the continuous variability of the ionosphere at a Spatio-temporal resolution which was unthinkable a few decades ago. We present unique characteristics of ionospheric wavenumber structures observed using COSMIC2 RO data, not reported before.

Recent Impact of COSMIC-2 with Improved Radio Occultation Data Assimilation Algorithms
Weather and Forecasting, 2023Abstract A Constellation Observing System for Meteorology, Ionosphere and Climate (COSMIC) follow-on constellation, COSMIC-2, was successfully launched into equatorial orbit on 24 June 2019. With an increased signal-to-noise ratio due to improved receivers and digital beam-steering antennas, COSMIC-2 is producing about 5000 high-quality radio ...

COSMIC-2: The future of global navigation satellite system - remote observation (GNSS-RO) sensing
2010 IEEE International Geoscience and Remote Sensing Symposium, 2010COSMIC is a joint U.S.-Taiwan 6-microsatellite demonstration mission that was launched in April 2006. It is the world's first operational GPS radio occultation (RO) mission for global Earth weather forecast; climate monitoring; atmospheric, ionospheric, and geodetic research.

Three-dimensional monitoring of Ionospheric storms using COSMIC-2 RO
High-rate Radio Occultation (RO) measurement using the COSMIC-2 constellation has enabled the observation of the transient changes in the ionosphere's three-dimensional (3D) structure.  This capability enables studying the changes to the 3D ionospheric structure during a geomagnetic storm.openaire +1 more source
