Modeling of gyrosynchrotron radio emission pulsations produced by MHD loop oscillations in solar flares [PDF]

open access: yes, 2011
A quantitative study of the observable radio signatures of the sausage, kink, and torsional MHD oscillation modes in flaring coronal loops is performed. Considering first non-zero order effect of these various MHD oscillation modes on the radio source parameters such as magnetic field, line of sight, plasma density and temperature, electron ...

Ionospheric Radio Occultation Measurements and Space Weather

open access: yes, 2004
GPS radio occultation measurements carried out on board Low Earth Orbiting (LEO) satellites provide a unique opportunity for monitoring the entire electron density distribution from LEO heights down to the bottom of the ionosphere. Furthermore, GPS navigation measurements onboard LEO’s may be used to reconstruct the electron density distribution of the

Benefits of a Closely-Spaced Satellite Constellation of Atmospheric Polarimetric Radio Occultation Measurements

open access: yesRemote Sensing, 2019
The climate and weather forecast predictive capability for precipitation intensity is limited by gaps in the understanding of basic cloud-convective processes.

Galileo ionosphere profile coincident with repeat plume detection location at Europa [PDF]

open access: yesarXiv, 2017
The location of a repeat plume detected at Europa is found to be coincident with the strongest ionosphere detection made by Galileo radio occultation in 1997.

Occultation of the Quiescent Emission from Sgr A* by IR Flares [PDF]

open access: yes, 2010
We have investigated the nature of flare emission from Sgr A* during multi-wavelength observations of this source that took place in 2004, 2005 and 2006. We present evidence for dimming of submm and radio flux during the peak of near-IR flares. This suggests that the variability of Sgr A* across its wavelength spectrum is phenomenologically related ...

Study of sporadic E layers based on GPS radio occultation measurements and digisonde data over the Brazilian region

open access: yes, 2018
. This work presents new results about sporadic E-layers (Es layers) using GPS (global positioning system) radio occultation (RO) measurements obtained from the FORMOSAT-3/COSMIC satellites and digisonde data.
