Limb Sounders Tracking Tsunami-Induced Perturbations from the Stratosphere to the Ionosphere

open access: yesRemote Sensing, 2022
In this study, we employ three types of satellite data from two different limb sounders: the FORMOSAT-3/COSMIC (F3/C) radio occultation (RO) technique and the Sounding of the Atmosphere using Broadband Emission Radiometry (SABER) instrument to study the ...

The Radiation Transfer at a Layer of Magnetized Plasma With Random Irregularities [PDF]

open access: yes, 1998
The problem of radio wave reflection from an optically thick plane monotonous layer of magnetized plasma is considered at present work. The plasma electron density irregularities are described by spatial spectrum of an arbitrary form.

Limb sounders tracking topographic gravity wave activity from the stratosphere to the ionosphere around midlatitude Andes [PDF]

open access: yes, 2015
Several studies have shown that the surroundings of the highest Andes mountains at midlatitudes in the Southern Hemisphere exhibit gravity waves (GWs) generated by diverse sources which may traverse the troposphere and then penetrate the upper layers if ...
