A new study shows that atmospheric gravity waves can be generated by the Kelvin-Helmholtz instabilities in the wind shear layer.
A new two-step Polar Mesospheric Cloud detection technique is applied towards the Himawari-8/Advanced Himawari Imager full-disk images leading to a new high-quality dataset.
Increased tropospheric heating and reduced dissipation combine to explain an anomalously large thermal tide.
Spacecraft observations support the mechanism for explaining auroral dunes observed from the ground by citizen scientists.
A shift in the tropopause jet may have triggered the unusual number of high-altitude clouds that briefly appeared in the early summer of 2019.
Scientists discuss geospace and what we could learn if we put some more eyes on this region in the atmosphere. Read more in our special themed issue.
Researchers have created thin, levitating disks that could be used to study the mesosphere, a layer of Earth’s atmosphere that’s difficult to reach with conventional flyers.
Night-shining clouds can be diagnostic tools to better understand how human activity is changing the meteorology of the mesosphere.
The auroral feature, first spotted by amateur astronomers in 2015, likely traces high-altitude atmospheric waves.
Ongoing climate change in Earth’s middle and upper atmosphere will affect the rapidly expanding space and telecommunications sectors. Maintaining observations of this region is more crucial than ever.
