On the determination of gravity wave momentum flux from GPS radio occultation data
Global Positioning System (GPS) radio occultation (RO) is a well-established technique for obtaining global gravity wave (GW) information. RO uses GPS signals received by low Earth-orbiting satellites for atmospheric limb sounding. Temperature profiles are derived with high vertical resolution and p...

| description | Global Positioning System (GPS) radio occultation (RO) is a well-established technique for obtaining
global gravity wave (GW) information. RO uses GPS signals received by low
Earth-orbiting satellites for atmospheric limb sounding. Temperature profiles
are derived with high vertical resolution and provide a global coverage under
any weather conditions, offering the possibility of global monitoring of the
vertical temperature structure and atmospheric wave parameters. The six-satellite constellation COSMIC/FORMOSAT-3 delivers approximately 2000
temperature profiles daily. In this study, we use a method to obtain global
distributions of horizontal gravity wave wavelengths, to be applied in the
determination of the vertical flux of horizontal momentum transported by
gravity waves. Here, a method for the determination of the real horizontal
wavelength from three vertical profiles is applied to the COSMIC data.
The horizontal and vertical wavelength, the specific potential energy
(<i>E</i><sub>p</sub>), and the vertical flux of horizontal momentum (MF) are
calculated and their global distribution is discussed. |
