The study of meteors has developed new relevance in recent years. This has been motivated by scientific interests as mundane as meteor ablation processes and the chemistry and state of the middle atmosphere, as fundamental as the origins and evolution of the earth and its environment and life, and as sublime as the possibility that life exists or existed elsewhere in the solar system or the galaxy. Motivation has also come from new techniques for recording the characteristics of meteor trails, using radar, optics, and ultrasound, and the new information these techniques have provided. This special issue contains a collection of papers that address the “mundaneȁd; of these issues, yet the conclusions are of fundamental importance to the study of the earth and its celestial environs. They deal with how and where meteoric material is deposited in the atmosphere and the chemistry that follows in order to form the metal layers in the mesosphere and lower thermosphere. It should be noted that we address issues that involve only the small portion of the total meteoric mass input (decoration:none; color:black"" href=""/science?_ob=MathURL&_method=retrieve&_udi=B6VHB-4GR344F-2&_mathId=mml1&_user=10&_cdi=6062&_rdoc=2&_handle=V-WA-A-W-AW-MsSAYVW-UUW-U-AABZBDUEDC-AABBECADDC-CAYYCBYWW-AW-U&_acct=C000050221&_version=1&_userid=10&md5=ebce8b5412cf5e160a203937202d1638"" title=""Click to view the MathML source"">μg–g particles) that is responsible for the phenomena discussed.
