TL;DR: In this article, the authors used observations of the Mars upper atmosphere made from the Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft to determine the loss rates of gas from the upper atmosphere to space for a complete Mars year (16 Nov 2014 − 3 Oct 2016).

TL;DR: A review of vertical coupling in the atmosphere and ionosphere system induced by internal waves of lower atmospheric origin is presented in this article, focusing on gravity waves, solar tides, planetary Rossby and Kelvin waves.

TL;DR: In this article, a parameterization of gravity wave (GW) drag, suitable for implementation into general circulation models (GCMs) extending into the thermosphere is presented, which systematically accounts for wave dissipation in the upper atmosphere due to molecular viscosity, thermal conduction, ion friction, and radiative damping in the form of the Newtonian cooling.

TL;DR: A conceptual discussion of plasma is first presented in this article, and various space plasma environments are discussed along with a brief introduction to the history of space research, and some key plasma parameters such as density, gyrofrequency, and temperature, and characteristics (collective motion, quasi-neutrality) are discussed concisely.

TL;DR: A review of recent developments in atmosphere-ionosphere science can be found in this article, focusing on the effects of internal waves, such as gravity waves and solar tides, sudden stratospheric warmings (SSWs), and of solar activity on the structure of the atmosphere.
