Data Quality Analysis of Wet Atmospheric Temperature Profiles from the YunYao Meteorological Constellation Radio Occultation
Radio occultation offers high vertical resolution, global coverage, and low sensitivity to clouds and precipitation, making it a useful complement to existing atmospheric sounding techniques. The YunYao constellation, the first commercial meteorological remote sensing constellation of China, supplies a large number of...

Operational Simulation and Validation of Slant-Path Atmospheric Transmittance at a High-Altitude Tibetan Site Using MERRA-2
This study evaluates operational optical to near-infrared (NIR) band (400–1050 nm) atmospheric transmittance simulation at the Ali-CPT site (5250 m above sea level). Monthly mean profiles from a 20-year Modern-Era Retrospective Analysis for Research and Applications, Version 2 (MERRA-2) reanalysis were combined with pr...

Evaluation of daily tropospheric radio refractivity, refractivity gradient and geoclimatic factor over Otukpo, Benue State, Nigeria
Radio refractivity is a key parameter for reliable terrestrial microwave-link design because the tropospheric propagation of radio waves is strongly affected by atmospheric refractive properties. Daily meteorological data spanning 23 years (2000--2022) were analysed to characterise surface radio refractivity (Ns), esti...

The Value of Radio Occultation Data in Global NWP: An OSSE on the Impact of Profile Volume, Geographical Distribution, and Satellite Bias Correction
An observing system simulation experiment framework was developed to quantify the impact of increasing the number and improving the distribution of radio occultation profiles on global numerical weather prediction (NWP) skill. Experiments were conducted assimilating between 6,000 and 100,000 daily radio occultation s...

Assimilating GNSS Airborne Radio Occultation Bending Angles With MPAS–JEDI During a Sequence of Atmospheric Rivers
Global Navigation Satellite System (GNSS) airborne radio occultation (ARO) observations, collected during Atmospheric River Reconnaissance (AR Recon) campaigns, enhance AR sampling beyond traditional dropsondes. Assimilating ARO bending angles requires a forward operator accounting for ARO geometry and proper integrati...
