SEEK-2 (Sporadic-E Experiment over Kyushu 2) is an observation campaign to study the
spatial structure of the field-aligned irregularity (FAI) and sporadic-E (E s)-layer by means of …

Using the Global Positioning System radio occultation (GPSRO) technique, the observation
of the global ionosphere becomes possible. The irregularity in the ionospheric sporadic‐E …

In this study, a two‐dimensional numerical model of the nonlinear Kelvin–Helmholtz (KH)
instability is used to investigate the nonlinear evolution processes of the ion layer, which is …

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 …

Abstract In December 2021 three Global Navigation Satellite System (GNSS) ionospheric
scintillation and Total Electron Content (TEC) monitors were installed in Puerto Rico (∼ …

Resonance Lidar observations of neutral sodium and VHF coherent scatter radar
observations of field‐aligned 3‐meter irregularities were obtained during the Coqui II rocket …

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 …

The low-altitude quasi-periodic (LQP) E-region echoes observed with the upgraded Hainan
COherent scatter Phased Array Radar (HCOPAR) located in Hainan Island of China (19.5° …

利用海南VHF 雷达(19.5 N, 109.1 E; 磁纬8.1 N) 在2011 年7 月15—22 日期间的连续观测数据,
对东亚低纬3m 尺度电离层场向不规则体(FAI) 特性进行了分析. 主要结果表明, 在整个观测期间 …

Highly structured electron densities in the E and F regions over Puerto Rico during the night
of February 20/21, 1999 were accompanied by intense coherent VHF radar backscatter from …
