Geophysics seminar: Eric Kuo-Nang Wang (IGPP) "Effects of heavy precipitation on single and dual polarization radio occultation (RO) observations"

Munk Conference Room
Event Description: 

Talk abstract:

Atmospheric moisture plays a significant role in the Earth’s weather system. However,
characterizing the near-surface moisture structure in extreme precipitation environment is a
challenging task since current remote sensing technology - infrared and microwave sounders -
cannot sense near the surface in the presence of heavy precipitation. In this presentation we
will introduce Global Positioning System (GPS) radio occultation (RO) technique and how its
high vertical resolution moisture observations are affected by heavy precipitations. We also
present the polarimetric RO (PRO) concept implemented by adding a dual-orthogonal
polarization measurement to the standard RO to detect and retrieve the extreme precipitation.
The encouraging results validated by the multiple phase screen (MPS) forward modeling shows
that this novel technique can observe vertical moist thermodynamic structure and heavy
precipitation simultaneously.
