The upper atmosphere as a research area encompasses the study of the mesosphere, thermosphere, and exosphere, including their composition, dynamics, energy balance, and coupling to both the lower atmosphere and near-Earth space. It focuses on processes such as radiative and conductive heating and cooling, wave propagation and breaking, ion-neutral interactions, atmospheric escape, and responses to solar and geomagnetic forcing. Research integrates in situ measurements, remote sensing, and numerical modeling to investigate phenomena like tides, gravity waves, noctilucent clouds, and space weather impacts on communication, navigation, and satellite drag.
For the first time, an international team of astronomers have mapped the vertical structure of Uranus's upper atmosphere, uncovering how temperature and charged particles vary with height across the planet. Using Webb's NIRSpec ...

We successfully plugged the hole in the ozone layer that was discovered in the 1980s by banning ozone-depleting substances such as chlorofluorocarbons (CFCs). But, it seems we might be unintentionally creating another potential ...

Between 50 and 100 kilometers (30–60 miles) above the Earth's surface lies a largely unstudied stretch of the atmosphere, called the mesosphere. It's too high for airplanes and weather balloons, too low for satellites, and ...

Between 50 and 1,000 kilometers above our heads is the ionosphere, a layer of Earth's upper atmosphere consisting of charged particles: ions (atoms that have gained or lost a negatively charged electron) and loose electrons. ...
