Upper Atmosphere

The upper atmosphere is one of the most sensitive shells embracing our planet. It is subject to impacts from both above (the Sun and magnetosphere) and below (tropospheric disturbances, earthquakes, and volcano eruptions). Its reactions to these impacts can be used for diagnostics of our environment, from the ground surface up to the magnetosphere and Sun. The upper atmosphere has a complex structure and composition, changing with altitude, from a mixture of neutral gases up to completely ionized space plasma. If the upper part (the thermosphere and ionosphere) can be monitored by both satellites and ground-based instruments, such as ionosondes and GPS receivers, the lower part, from 50 up to 80 km, is difficult to monitor; this is why papers describing new technologies of the lower part of the upper atmosphere are welcomed.

We welcome publications describing the upper atmosphere dynamics in different solar and geomagnetic conditions, as well as those stimulated by effects from below. Methods for upper ionosphere monitoring, as well as papers concerned with the modeling of physical processes, are invited. Download Section Flyer
