GNSS-RO Refractivity Bias Correction Under Ducting Layer Using Surface-Reflection Signal [PDF]
Remote Sensing, 2020 Due to its high vertical resolution and cloud-penetrating capability, GNSS-Radio Occultation (RO) remote sensing technique has been utilized to observe the vertical structure of the Planetary Boundary Layer (PBL) in recent years. However, the critical refraction, or ducting, caused by large refractivity gradients usually associated with the top of the ...
