Implication

Technical review demonstrates global ionospheric electron density profiling using COSMIC GPS occultations, indicating improved capabilities for continuous space weather forecasting.

Key Points

To describe the utility of the COSMIC GPS radio occultation satellite constellation for continuous, global ionospheric sensing and space weather forecasting.
Evaluated radio occultation geometry using a low-Earth orbit constellation of GPS receivers providing nearly 5,600 occultation measurements per day.
Assessed retrieval methodologies spanning Abel inversion, gradient-constrained Abel inversion, 3-D tomography, and data assimilation using GPS/MET observations.
Individual GPS occultation soundings yield vertical electron density profiles with approximately 1-km vertical resolution.
Collective occultation data processing through tomography and data assimilation enables continuous 3-D imaging of electron density, irregularities, and traveling ionospheric disturbances.
