A meteoroid penetrating the Earth’s atmosphere leaves behind a trail
of dense plasma embedded in the lower E/upper D-region ionosphere. While
radar measurements of meteor trail evolution have been c...

High‐power large‐aperture (HPLA) radars frequently observe nonspecular meteor trail
echoes that result from plasma turbulence driven by the intense pressure gradients on
the trail edges. This paper ...

When meteor-generated plasma trails diffuse into the
ionosphere they create large ambipolar electric fields
mainly perpendicular to the Earth’s geomagnetic field
(B) and extending many kilometers f...
Ground-based radio observations to probe the ozone content in the meteor region

Great Meteor Seamount
2015/7/7
Great Meteor Seamount is one of the largest seamounts in the Atlantic Ocean, rising from 4200-m depth at the seafloor to 270-m depth beneath the sea surface (Figure 1). Its elliptical plateau encompas...
Interpretation of non-specular radar meteor trails
radar meteor trails consistent features
2017/3/22
Radar data of non-specular meteor trails shows two
clear and consistent features: (1) non– specular meteor trails
are observed from a narrower altitude range than are head
echoes and (2) an approxi...

High‐power, large‐aperture (HPLA) radars have been used over the past two decades
to characterize the plasmas formed both around and behind meteoroids as they enter
Earth’s atmosphere. These plasmas...
