Measurements of vertical eddy diffusivity across the tropopause using radio acoustic sounding system (RASS) [PDF]

open access: yesGeophysical Research Letters, 2007
A four day high temporal resolution MU radar RASS data set was obtained under light wind conditions in August 1995, enabling retrieval of virtual temperatures up to 20 km. This provided a unique opportunity to study the vertical eddy diffusivity K across the tropopause using RASS Brunt‐Väisälä frequency N and radar spectral width. Co‐located six hourly

On the determination of gravity wave momentum flux from GPS radio occultation data [PDF]

open access: yesAtmospheric Measurement Techniques, 2013
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.
