Radar studies of mid-latitude ionospheric plasma drifts
We use incoherent scatter radar measurements from Millstone Hill and Saint Santin to study the midlatitude F region electrodynamic plasma drifts during geomagnetically quiet and active periods. We present initially a local time, season, and solar flux dependent analytical model of the quiet time zonal and meridional ExB drifts over these stations. We discuss, for the first time, the Saint Santi...
متن کاملNumerical simulation of mid-latitude ionospheric E-region based on SEEK and SEEK-2 observations
Observational campaigns of the mid-latitude ionosphericE-region with sounding rockets and ground-based instruments were conducted in 1996 (SEEK) and 2002 (SEEK2). Both of them were successfully conducted to bring important findings about the mid-latitude E-region and quasiperiodic (QP) VHF radar echoes. The observational results in the SEEK and the SEEK-2 are compared with numerical simulations...
متن کاملObservations of Pc 3-4 and Pi 2 geomagnetic pulsations in the low-latitude ionosphere
Day-time Pc 3-4 ( 5±60 mHz) and nighttime Pi 2 ( 5±20 mHz) ULF waves propagating down through the ionosphere can cause oscillations in the Doppler shift of HF radio transmissions that are correlated with the magnetic pulsations recorded on the ground. In order to examine properties of these correlated signals, we conducted a joint HF Doppler/ magnetometer experiment for two six-month intervals ...
متن کاملGlobal observation of 24 November 2006 Pc5 pulsations by single mid-latitude underground [SQUID]2 system
On 24 November 2006, simultaneous observations of Pc5 pulsations, electron precipitation and whistlermode chorus, as well as solar wind and IMF parameters have been analyzed based on data from IMAGE magnetometers, riometer array and temporal VLF station. This paper focuses on the Pc5 pulsations detected at the same time, in the 1–25 millihertz range, by the [SQUID]2 system (SQUID magnetometer w...
متن کاملThe role of ionospheric clutter in mid-latitude and arctic regions for assessment of HFSWR surveillance
The ionosphere is the region of the earth’s atmosphere in which gases are ionized by radiation such as ultraviolet light from the sun and cosmic rays from outer space. The unwanted radar echoes from the ionosphere are collectively called ionospheric clutter. This paper studies the arctic and mid-latitude ionospheric environment using ionosonde data and assesses High-Frequency Surface-Wave Radar...
