On associations of Apollo asteroids with meteor streams [PDF]

open access: yes
Potential associations of Apollo asteroids with meteor streams are searched on the basis of the orbital parameters comparison. From all Apollo asteroids discovered through 1991 June those are only selected for further analysis whose orbits approach to ...

Density variations of meteor flux along the Earth's orbit [PDF]

open access: yes
No model of distribution of meteor substance is known to explain the observed diurnal and annual variations of meteor rates, if that distribution is assumed to be constant during the year.

Diurnal variation of overdense meteor echo duration and ozone [PDF]

open access: yes
The diurnal variation of the median duration of overdense sporadic radar meteor echoes is examined. The meteors recorded in August, December, and January by the Ondrejov meteor radar during the period 1958-1990 were used for the analysis.

An introduction to the Meteor and ionospheric Irregularity Observation System and its preliminary results

open access: yes地球与行星物理论评
Meteoroids entering the Earth's atmosphere lose most of their mass during atmospheric passage and considerably disturb the background ionosphere. To elucidate better the effects of meteoroids on the near-Earth space environment, it is important to ...
