TL;DR: A global survey of airbursts of a kiloton or more is performed, and it is found that the number of impactors with diameters of tens of metres may be an order of magnitude higher than estimates based on other techniques, which suggests a non-equilibrium in the near-Earth asteroid population.
Journal ArticleDOI
Model of the ablation of faint meteors
TL;DR: In this paper, a model of meteor ablation in the atmosphere has been developed for meteoroids in the mass range 10 −12 kg to 4 × 10 −5 kg (size range 10 µm to 2 mm).
Journal ArticleDOI
The Canadian Meteor Orbit Radar: system overview and preliminary results
J. Jones,Peter Brown,K. J. Ellis,A. R. Webster,Margaret Campbell-Brown,Z. Krzemenski,Robert Weryk +6 more
TL;DR: The purpose of this paper is to show that the radiants and speeds necessary for the computation of orbits are well measured rather than to discuss any orbital surveys.
Journal ArticleDOI
A dynamical model of the sporadic meteoroid complex
TL;DR: In this paper, a physics-based model of the Earth's meteoroid complex is presented, which uses the observed meteor patrol radar strengths of the sporadic meteors to solve for the dust production rates of the populations of comets modeled.
Journal ArticleDOI
High resolution radiant distribution and orbits of sporadic radar meteoroids
TL;DR: In this article, the authors used five years of meteor orbit data from CMOR (the Canadian Meteor Orbit Radar) to study the high-resolution orbital structure of the sporadic meteoroid complex.
