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 کاملMulti-technique Studies of Ionospheric Plasma Structuring
The day-to-day variability in ionospheric irregularity generation giving rise to equatorial scintillation has remained an unresolved issue over many decades (Basu and Basu, 1985). We take a fresh look at the problem utilizing the global imagery provided by the GUVI instrument on NASA’s TIMED satellite. GUVI has been acquiring images of 135.6-nm emission in the Earth’s ionosphere/thermosphere sy...
متن کاملData assimilation of incoherent scatter radar observation into a one-dimensional midlatitude ionospheric model by applying ensemble Kalman filter
[1] In this paper, electron densities during 25–28 September 2000 observed by the Millstone Hill incoherent scatter radar (ISR) are assimilated into a one-dimensional midlatitude ionospheric theoretical model by using an ensemble Kalman filter (EnKF) technique. It is found that (1) the derived vertical correlation coefficients of electron density show obvious altitude dependence. These variatio...
متن کاملA survey of plasma irregularities as seen by the midlatitude Blackstone SuperDARN radar
[1] The Super Dual Auroral Radar Network (SuperDARN) is a chain of HF radars that monitor plasma dynamics in the ionosphere. In recent years, SuperDARN has expanded to midlatitudes in order to provide enhanced coverage during geomagnetically active periods. A new type of backscatter from F region plasma irregularities with low Doppler velocity has been frequently observed on the nightside durin...
