Mapping plasma structures in the high-latitude ionosphere using beacon satellite, incoherent scatter radar and ground-based magnetometer observations
Beacon satellites ionospheric plasma
2015/9/25
In the autumn of the year 2000, four radio receivers capable of tracking various beacon satellites were set up along the southwestern coast of Greenland. They are used to reconstruct images of the ion...
A revised method to extract thermospheric parameters from incoherent scatter observations
thermospheric ionization
2015/9/14
Height distribution of ionospheric plasma parameters in the F2-region is closely related to height distribution of the main thermospheric parameters. Therefore, they can be extracted from ionospheric ...
Observations of surface radiation and stratospheric processes at Thule Air Base, Greenland, during the IPY
Polar atmosphere NDACC Radiative budget Stratospheric ozone
2015/8/17
Ground-based measurements of atmospheric parameters have been carried out for more than 20 years at the Network for the Detection of Atmospheric Composition Change (NDACC) station at Thule Air Base (7...
Very Large Array Observations of Disturbed Ion Flow from the Plasmasphere to the Nighttime Ionosphere
Array Observations of Disturbed Ion Nighttime Ionosphere Space Physics
2012/5/29
We present the results of a multi-scale analysis of TEC fluctuations using a roughly five-hour observation of the bright radio source Virgo A with the Very Large Array (VLA) at 74 MHz in its B configu...
Nonlinear features of equatorial baroclinic Rossby waves detected in Topex altimeter observations
Nonlinear features equatorial baroclinic Rossby waves Topex altimeter observations
2009/11/16
Using a recently proposed technique for statistical analysis of non-gridded satellite altimeter data, regime of long equatorially-trapped baroclinic Rossby waves is studied. One-dimensional spatial an...
Nonlinear evolution of the parametric instability:numerical predictions versus observations in the heliosphere
Nonlinear evolution parametric instability numerical predictions versus observations
2009/11/12
Low-frequency turbulence in the solar wind is characterized by a high degree of Alfvénicity close to the Sun. Cross-helicity, which is a measure of Alfvénic correlation, tends to decrease with increas...
Large amplitude solitary waves in and near the Earth’s magnetosphere,magnetopause and bow shock:Polar and Cluster observations
Large amplitude solitary waves Earth’s magnetosphere magnetopause bow shock
2009/11/11
Solitary waves with large electric fields (up to 100's of mV/m) have been observed throughout the magnetosphere and in the bow shock. We discuss observations by Polar at high altitudes ( ~ 4-8 RE ), d...
Multi-point observations of intermittency in the cusp regions
Multi-point observations intermittency cusp regions
2009/11/3
In this paper we investigate the statistical properties of magnetic field fluctuations measured by the four Cluster spacecraft in the cusp and close to the interface with the magnetospheric lobes, mag...
Plasma waves above the ion cyclotron frequency in the solar wind:a review on observations
Plasma waves ion cyclotron frequency solar wind
2009/10/30
Since the very beginning of the space venture, discrepancies between hydrodynamic models and observations have raised the attention to the kinetic effects taking place in the interplanetary medium. Af...

Observations Inhomogeneities and Detection of Climate Change
Climatological time series homogenization sequential statistical analysis change-point search joint significance levels climate evolution
2009/6/10
It is now well known that inhomogeneities in observations and climate instability have the
common statistical property of producing generally in climatological series abrupt changes in the distributi...
Geomagnetic Observations at Sodankylä During the First International Polar Year
Geomagnetic observations Polar Year
2009/6/10
Sodankylä was one of the 11 stations that were in operation during the First International Polar Year 1882-1883. In this study we re-analyze the magnetic observations carried out in Sodankylä...

Ionosphere Space plasma physics
2017/3/22
Low frequency electrostatic waves in the lower
parts of the ionosphere are studied by a comparison of observations
by instrumented rockets and of results from numerical
simulations. Particular atte...
