Statistically analyzing the effect of ionospheric irregularity on GNSS radio occultation atmospheric measurement [PDF]
Atmospheric Measurement Techniques, 2021 The Global Navigation Satellite System (GNSS) atmospheric radio occultation (RO) has been an effective method for exploring Earth's atmosphere. RO signals propagate through the ionosphere before reaching the neutral atmosphere.

Effect of GNSS RO on prediction of the 2021 Henan Rainstorm
, 2022 Abstract Precise prediction of the extremely heavy rainstorm is still challenging due to less or low spatial-temporal measurements. Nowadays, space-borne Global Navigation Satellite System (GNSS) radio occultation (RO) provides high spatial-resolution atmospheric parameters, which may improve the prediction precision of heavy rainfalls. In this
