The subject of this review is the atmospheric chemistry of the metals which ablate from
meteoroids in the Earth, s upper atmosphere. The major meteoric species are Fe, Mg, Si …

A detailed overview of long‐term secular trends in temperature of the mesosphere and lower
thermosphere considered to be induced by increase in greenhouse gases has been …

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

We have updated long‐term trends in mesopause temperature, airglow emission intensities,
and noctilucent clouds (NLCs) based on ground‐based observations conducted in the …

Satellite observations of polar mesospheric clouds (PMCs) are extremely valuable because
they typically have daily coverage to characterize seasonal variations, sufficient detections …

The mesosphere/lower thermosphere (MLT, 80–100 km) region is an important boundary
between Earth's atmosphere below and space above and may act as a sensitive indicator …

The natural variability in the terrestrial mesosphere needs to be known to correctly quantify
global change. The response of the thermal structure to solar activity variations is an …

Temperature profiles from two satellite instruments–TIMED/SABER and Aura/MLS–have
been used to calculate hydroxyl-layer equivalent temperatures for comparison with values …

The global distribution of traveling planetary wave (PW) activity in the mesopause region is
estimated for the first time from ground-based airglow measurements. Monthly and total …

Parameterization schemes of atmospheric normal modes (NMs) and orographic gravity
waves (OGWs) have been implemented into the mechanistic Middle and Upper Atmosphere …
