The subject of this review is the atmospheric chemistry of the metals that ablate from
meteoroids at altitudes between 70 and 120 km in the Earth's atmosphere. Before describing …

Laser Remote Sensing provides an up-to-date, comprehensive review on LIDAR, focusing
mainly on applications to current topics in atmospheric science. The scope of the book …

The book summarizes international progress over the last few decades in upper atmosphere
airglow research. Measurement methods, theoretical concepts and empirical models of a …

This paper describes a laboratory study into the chemical pathways by which Na+ is
converted to Na in the upper atmosphere. The termolecular clustering reactions of Na+ with …

We report on a comprehensive set of observations of the upper atmospheric Ca and Ca+
layers. The observations were obtained by ground‐based lidars at Kühlungsborn, Germany …

A complete monthly record of the annual variation of Na and temperature in the upper
mesosphere has been obtained from 3 years of nighttime lidar observations at two …

Characteristics of the sporadic sodium layers (SSLs or Na S) in different latitudes and
altitudes are summarized in this paper and the possible mechanisms are discussed. The …

Lidar observations, conducted at the South Pole by University of Illinois researchers, are
used to characterize the seasonal variations of mesospheric Na and Fe above the site. The …

The layers of neutral metal atoms such as Na and Fe, which occur in the mesosphere and
lower thermosphere as a result of meteoric ablation, can be observed with excellent spatial …
