Polarization Changes of Radio Signals in Vertical Radio-Echo Sounding of Glaciers [PDF]
An electromagnetic linearly-polarized signal transmitted through the glacier in a vertical direction, reflected from the bedrock, and received with a receiving antenna, is found to be changed into one either partially or elliptically polarized. The polarization changes are believed to be due mainly to the crystal structure of the glacier and anisotropy

Measurements of vertical eddy diffusivity across the tropopause using radio acoustic sounding system (RASS) [PDF]
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 distortions in calculated GW parameters during slanted atmospheric soundings [PDF]
The significant distortions introduced in the measured atmospheric gravity wavelengths by soundings other than those in vertical and horizontal directions, are discussed as a function of the elevation angle of the sounding path and the gravity wave ...
