Meteor trail diffusion and fields: 1. Simulations
(American Geophysical Union, 2006-12-20)
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 collected and used to ...
An orbital meteoroid stream survey using the Southern Argentina Agile MEteor Radar (SAAMER) based on a wavelet approach
(Academic Press Inc Elsevier Science, 2017-07)
Over a million individually measured meteoroid orbits were collected with the Southern Argentina Agile MEteor Radar (SAAMER) between 2012–2015. This provides a robust statistical database to perform an initial orbital ...
First definitive observations of meteor shower particles using a high-power-large-aperture radar
(Elsevier, 2008-03)
We present the first clear observations of meteor shower activity from meteor-head echoes detected by a high-power large-aperture radar (HPLAR). Such observations have been performed at the Jicamarca VHF radar using its ...
Interferometric meteor head echo observations using the Southern Argentina Agile Meteor Radar
(American Geophysical Union, 2014-02)
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 mechanisms exist: specular, nonspecular ...
Meteor trails track upper atmospheric winds
(American Institute of Physics, 2009-06-01)
Meers Oppenheim and his colleagues from Boston University, Peru's Jicamarca Radio Observatory (JRO), and Los Alamos National Laboratory now offer an alternative approach that has its origins in another 50-year-old technique. ...
Meteor-head echo observations using an antenna compression approach with the 450 MHz Poker Flat Incoherent Scatter Radar
(Elsevier, 2009-05)
In this work we present a novel use of the Poker Flat Incoherent Scatter Radar (PFISR) to study meteor-head echoes with wide (W) beams. Until now, most of the meteor-head echo studies have been performed with High-Power ...
Simultaneous optical and radar observations of meteor head-echoes utilizing SAAMER
(Elsevier, 2015-12)
We present simultaneous optical and radar observations of meteors observed with the Southern Argentine Agile MEteor Radar (SAAMER). Although such observations were performed in the past using High Power and Large Aperture ...
Solving Long-Standing meteor mysteries
(The Pennsylvania State University, 2009-08)
Millions of meteoroids strike and disintegrate in the Earth's upper atmosphere every day and may be seen as visible or radar meteors. Although very few of the these foreign bodies actually make it to the surface of the ...
High-altitude radar meteors observed at Jicamarca Radio Observatory using a multibaseline interferometric technique
(Royal Astronomical Society, 2015-08-11)
A new unambiguous, multibaseline interferometric technique was recently employed for meteor observations at Jicamarca Radio Observatory (JRO). These observations largely confirm high-altitude radar meteors (HARMs). The 50 ...
