Study of dynamics of minor constituents in the thermosphere, addendum [PDF]

Numerical studies of a model of the earth's thermosphere are presented. The distribution of thermospheric helium was investigated. Changes in the global transport of helium under solstice conditions caused by a small increase in the latitudes at which ...

EnviroNET: Space environment for Strategic Defense Initiative experiments [PDF]

EnviroNET is an operational system available to the Strategic Defense Initiative (SDI) experimenters who have access to a terminal or dial-up port. It is a tail node on Space Physics Analysis Network (SPAN) accessible directly or through the national ...

Evidence of a saturated gravity-wave spectrum throughout the atmosphere [PDF]

, 1986
The view adapted here is that the dominant mesoscale motions are due to internal gravity waves and show that previous and new vertical wave number spectra of horizontal winds are consistent with the notion of a saturation limit on wave amplitudes.

Observation of vertical coupling during a major sudden stratospheric warming by ICON and GOLD: a case study of the 2020/2021 warming event

Frontiers in Astronomy and Space Sciences
The response of the thermospheric daytime longitudinally averaged zonal and meridional winds and neutral temperature to the 2020/2021 major sudden stratospheric warming (SSW) is studied at low-to middle latitudes (0◦ - 40◦N) using observations by NASA’s ...

Mean pressure distribution and geostrophic circulation in the meteor zone [PDF]

Boutko et al., used available satellite radiometer data to estimate 0.1 mb constant pressure heights in the mesosphere and Koshelkov and Kovshova derived, 0.1 to 0.005 mb or 0.1 to 0.001 mb layer thickness from which were compiled height fields of the 0 ...

Self-consistent modelling of the polar thermosphere and ionosphere to magnetospheric convection and precipitation (invited review) [PDF]

It has recently been demonstrated that the dramatic effects of plasma precipitation and convection on the composition and dynamics of the polar thermosphere and ionosphere include a number of strong interactive, or feedback, processes.

Resolving thermospheric vertical wind ambiguities and energy processes

Frontiers in Astronomy and Space Sciences
This study applies a generalized vertical coordinate system approach alongside thermodynamic control volume analysis to explore the nuanced interpretations of energy transfer processes associated with vertical motion in the thermosphere.
