Spectra of Acoustic-Gravity Waves in the Atmosphere with a Quasi-Isothermal Upper Layer
In this paper, we study, in theoretical terms, the structure of the spectrum of acoustic-gravity waves (AGWs) in the nonisothermal atmosphere having asymptotically constant temperature at high altitudes.

Sublimation of ice particles from rocket exhausts in the upper atmosphere [PDF]
The process of sublimation of ice particles from a rocket exhaust in the upper atmosphere is examined. Heating by solar radiation and losses of energy by means thermal radiation and sublimation are taken into account in the thermal balance of the ice ...

Modelling high-latitude electron densities with a coupled thermosphere-ionosphere model [PDF]
A few of the difficulties in accurately modelling high-latitude electron densities with a large-scale numerical model of the thermosphere and ionosphere are addressed by comparing electron densities calculated with the Coupled Thermosphere-Ionosphere ...

Segmentation of PMSE Data Using Random Forests
EISCAT VHF radar data are used for observing, monitoring, and understanding Earth’s upper atmosphere. This paper presents an approach to segment Polar Mesospheric Summer Echoes (PMSE) from datasets obtained from EISCAT VHF radar data. The data consist of
