All‐sky radar measurements provide a unique capability to resolve the spatial structure of E
region irregularities over a large zonal region. With the all‐sky radar interferometry …

A 30 MHz radar has recently been established at Gadanki (13.5° N, 79.2° E; 6.5° N magnetic
latitude) to make unattended observations of the ionospheric field‐aligned irregularities …

Abstract Sanya VHF radar (18.4° N, 109.6° E, dip latitude 12.8° N) at Hainan Island is the
first coherent backscatter radar for sounding low-latitude ionospheric irregularities in the …

All‐sky interferometric meteor radar has been operated worldwide for the measurements of
neutral winds in the mesopause region. In this paper, we employ an all‐sky meteor radar …

We report for the first time a case of wavelike structures of E‐region irregularities observed
by an all‐sky radar at Ledong (18.44° N, 108.97° E), China. The wavelike structures covered …

Study of Atmospheric Forcing and Responses (SAFAR) is a five year (2009–2014) research
programme specifically to address the responses of the earth's atmosphere to both natural …

Statistical characteristics of the E‐region irregularities observed by the HCOPAR in the low‐
latitudes of China are presented and analyzed. The data come from the observations …

The Hainan coherent scatter phased array radar (HCOPAR) is one of the most important
radio systems of the Chinese Meridian Space Weather Monitoring Project (Meridian Project) …

The special daytime echoes, which present the V‐shaped echo pattern between 90–180 km
ranges in the range‐time‐intensity (RTI) plot, were occasionally recorded by the Hainan …

The Arecibo Observatory (AO) is a multidisciplinary research and education facility that is
recognized worldwide as a leading facility in astronomy, planetary, and atmospheric and …
