Abstract The Meteor and ionospheric Irregularity Observation System (MIOS), which consists
of multi‐station optical subsystem at Ledong (18.4° N, 109° E) and Sanya (18.3° N, 109.6° …

A radar meteor echo is the radar scattering signature from the free electrons generated by
the entry of extraterrestrial particles into the atmosphere. Three categories of scattering …

Meteoroids entering the Earth's atmosphere produce ionized trails, which are detectable by
radio sounding. Cylindrical underdense (and partly overdense) trails form a great majority of …

The meteor trail echo decay rates are analysed on-site to provide daily temperatures near
90 km. In order to get temperatures from trail decay times, either knowledge of the pressure …

Using data from the Sodankylä Geophysical Observatory (67° 22′ N, 26° 38′ E, Finland)
meteor camera from the whole year 2015, we identified and investigated 28 optical meteors …

Given the current limited knowledge of meteor plasma micro-physics and its interaction with
the surrounding atmosphere and ionosphere, meteors are a highly interesting observational …

Radars detect plasma trails created by the billions of small meteoroids that enter the Earth's
atmosphere daily, returning data used to infer characteristics of the meteoroid population …

Non-specular meteor trail echoes are radar reflections from plasma instabilities that are
caused by field-aligned irregularities. Meteor simulations are examined to show that these …

We present observations of 86 meteor radio afterglows (MRAs) using the new broadband
imager at the Long Wavelength Array Sevilleta (LWA‐SV) station. The MRAs were detected …

Sporadic sodium (Na s) layers, occurring in roughly the same height range as ionospheric
sporadic-E layers, were first detected by lidar some 30 yr ago. Na s layers have a typical …
