3-D reconstructions of the early-November 2004 CDAW geomagnetic storms: analysis of Ooty IPS speed and density data [PDF]

Annales Geophysicae, 2009
Interplanetary scintillation (IPS) remote-sensing observations provide a view of the solar wind covering a wide range of heliographic latitudes and heliocentric distances from the Sun between ~0.1 AU and 3.0 AU. Such observations are used to study the

The solar causes of major geomagnetic storms [PDF]

Annales Geophysicae, 1994
In this paper we reanalyse the set of ten major geomagnetic storms which occurred between August 1978 and December 1979. We relate them to the characteristics of the solar wind disturbances which caused them and the solar sources of such disturbances ...

Probabilistic forecasting of ionospheric scintillation and GNSS receiver signal tracking performance at high latitudes

Annals of Geophysics, 2013
At high latitudes, phase scintillation occurs predominantly on the dayside in the ionospheric footprint of the magnetospheric cusp, and in the nightside auroral oval. A new technique of probabilistic forecasting of phase scintillation occurrence relative

Observations of interplanetary scintillation during the 1998 Whole Sun Month: a comparison between EISCAT, ORT and Nagoya data [PDF]

Annales Geophysicae, 2000
Observations of interplanetary scintillation (IPS) allow accurate solar wind velocity measurements to be made at all heliographic latitudes and at a range of distances from the Sun.

An Anisotropic Density Turbulence Model from the Sun to 1 au Derived from Radio Observations

The Astrophysical Journal, 2023
Solar radio bursts are strongly affected by radio-wave scattering on density inhomogeneities, changing their observed time characteristics, sizes, and positions.

INFLUENCE OF THE SOLAR WIND ON INTERFEROMETRIC OBSERVATIONS AT THE DECAMETER WAVELENGTHS [PDF]

Radio Physics and Radio Astronomy, 2020
Purpose: The effect of the Earth’s ionosphere and interplanetary plasma on the radio astronomy observations, in particular, interferometric ones, at decameter waves has been investigated.

Interplanetary scintillation and pulsar pulse statistics

Monthly Notices of the Royal Astronomical Society, 2023
ABSTRACT The effect of interplanetary plasma on pulsed pulsar radiation passing through is considered. The pulses of two rotating radio transients (J0609+16 and J1132+25) and a pulsar (B0320+39) detected on the Large Phased Array (Pushchino observatory) were analysed.

Observation of Interplanetary Scintillation with Single-Station Mode at Urumqi

, 2010
The Sun affects the Earth's physical phenomena in multiple ways, in particular the material in interplanetary space comes from coronal expansion in the form of inhomogeneous plasma flow (solar wind), which is the primary source of the interplanetary ...
