Electron density and temperature measurements in the cold plasma environment of Titan: Implications for atmospheric escape
(American Geophysical Union, 2010-10)
We present electron temperature and density measurements of Titan's cold ionospheric plasma from the Langmuir probe instrument on Cassini from 52 flybys. An expression of the density as a function of temperature is presented ...
Possible ionospheric preconditioning by shear flow leading to equatorial spread F
(European Geosciences Union (EGU), 2005-10-14)
Vertical shear in the zonal plasma drift speed is apparent in incoherent and coherent scatter radar observations of the bottomside F region ionosphere made at Jicamarca from about 1600–2200 LT. The relative importance of ...
CIGALA: Challenging the solar maximum in Brazil with PolaRxS
(2011-12-01)
The upcoming solar maximum, which is expected to reach its peak around May 2013, occurs at a time when our reliance on high-precision GNSS has reached unprecedented proportions. The perturbations of the ionosphere caused ...

Low latitude scintillations: A comparison of modeling and observations within the CIGALA project
(2011-11-21)
Ionospheric scintillations can seriously jeopardize the reliability of the GNSS signals and consequently can cause significant error or outage on precise positioning applications. The threat is most acute at low latitudes ...

Stormtime dynamics of the global thermosphere and equatorial ionosphere
(European Geosciences Union, 2009-05-05)
During magnetic storms the development of equatorial plasma bubbles (EPBs) and distributions of thermospheric densities are strongly influenced by the histories of imposed magnetospheric electric (εM) fields. Periods of ...
Towards forecasting and mitigating ionospheric scintillation effects on GNSS
(Ieee, 2007-01-01)
The effect of the ionosphere on the signals of Global Navigation Satellite Systems (GNSS), such as the Global Positionig System (GPS) and the proposed European Galileo, is dependent on the ionospheric electron density, ...
East-west ionospheric drifts at the magnetic equator
(Instituto Geofísico del Perú, 1972-01-01)
A technique has been developed to measure the electromagnetic east-west drift velocity of the F region ionosphere by means of the Jicamarca incoherent scatter radar. Results show a fairly consistent behavior from day to ...
