The 2011 October Draconids Outburst. II. Meteoroid Chemical Abundances from Fireball Spectroscopy [PDF]

, 2013
On October 8, 2011 the Earth crossed dust trails ejected from comet 21P/Giacobini-Zinner in the late 19th and early 20th Century. This gave rise to an outburst in the activity of the October Draconid meteor shower, and an international team was organized

The METCRAX II Field Experiment: A Study of Downslope Windstorm-Type Flows in Arizona\u2019s Meteor Crater [PDF]

, 2016
The second Meteor Crater Experiment (METCRAX II) was conducted in October 2013 at Arizona\u2019s Meteor Crater. The experiment was designed to investigate nighttime downslope windstorm 12type flows that form regularly above the inner southwest sidewall ...

Ground-based radio observations to probe the ozone content in the meteor region

Annals of Geophysics, 2003
Radar studies of the plasma irregularities produced by meteoroid ablation provide a powerful diagnostic probe of the Earth's atmosphere. This role is especially important as an inexpensive route for studying several atmospheric processes in comparison ...

Meteor matter interaction with the Earth's atmosphere and the ionospheric E-region structure [PDF]

The exploration of the ionospheric E region is a pressing problem, both in the applied and fundamental studies. Results are presented of an investigation: (1) to estimate the meteor ionization contribution to the night time E layer and influx; (2) to ...

On the meteor trail spectra [PDF]

Meteor radiation appears as a result of collisions between meteoroid atoms and air molecules. Depending on duration, this radiation is usually divided into the following types: radiation of the meteor head; radiation of a coma surrounding or immediately ...

Meteor velocity determination with plasma physics [PDF]

Atmospheric Chemistry and Physics, 2004
Understanding the global meteor flux at Earth requires the measurement of meteor velocities. While several radar methods exist for measuring meteor velocity, they may be biased by plasma reflection mechanisms.

Determination of meteor flux distribution over the celestial sphere [PDF]

A new method of determination of meteor flux density distribution over the celestial sphere is discussed. The flux density was derived from observations by radar together with measurements of angles of arrival of radio waves reflected from meteor trails.

Two-dimensional wind field observation based on multistatic meteor radars in central and eastern China

地球与行星物理论评
All-sky meteor radars have become a reliable and widely used tool for observing horizontal winds in the mesosphere and lower thermosphere (MLT) region. This provides vital data support for the study of dynamics in this region.
