The 30‐MHz radar observations of coherent scatter from midlatitude E region plasma
irregularities are presented and interpreted. Our analysis indicates that quasiperiodic (QP) …

Abstract Space weather, just like its meteorological counterpart, is of extreme importance
when it comes to its impact on terrestrial near‐and far‐space environments. In recent years …

We present a summary of the statistical characteristics of echoes from ionospheric (E-and F-
region) field-aligned irregularities obtained with the Piura VHF radar. This radar is located …

The statistical characteristics of E-region field-aligned irregularities observed with the
Gadanki MST radar are presented and compared with observations made with the Piura …

This paper presents the first observations of lower E region echoes made with the Equatorial
Atmosphere radar (EAR) located in West Sumatra, Indonesia (0.2° S, 100.32° E; dip latitude …

This is a report of so far undescribed equatorial quasiperiodic (EQP) echoes from field‐
aligned irregularities from the E and lower F region. These echoes were observed on …

The new theory of sporadic E density oscillation with double atmospheric gravity wave
(AGW) frequency in two-dimensional case taking into account ions ambipolar diffusion is …

We present and analyze some interesting new aspects of low‐latitude quasi‐periodic (QP)
echoes observed using the Gadanki radar, not reported before, to address the origin of …

Analyzing the field‐aligned coherent radar backscatter observed over Gadanki, India (13.5°
N, 79.2° E), with a narrow beam pointing almost vertically, we present convincing …

The geomagnetically low‐latitude valley region between the upper E region and the lower
F1 region is studied with the Equatorial Atmosphere Radar (EAR) in Indonesia. Three‐meter …
