Effects of a mid-latitude solar eclipse on the thermosphere and ionosphere - A modelling study [PDF]

open access: yes, 1998
A modelling study is presented which investigates in-situ generated changes of the thermosphere and ionosphere during a solar eclipse. Neutral temperatures are expected to drop by up to 40 degrees K at 240 km height in the totality footprint, with ...

Impacts of Lower Thermospheric Atomic Oxygen on Thermospheric Dynamics and Composition Using the Global Ionosphere Thermosphere Model [PDF]

open access: yesJournal of Geophysical Research: Space Physics, 2020
AbstractThe exchange of energy between the lower atmosphere and the ionosphere thermosphere system is not well understood. One of the parameters that is important in the lower thermosphere is atomic oxygen. It has recently been observed that atomic oxygen is higher in summer at ∼95 km.

Swarm A and C Accelerometers: Data Validation and Scientific Interpretation

open access: yesEarth and Space Science, 2023
The fourth European Space Agency Earth Explorer (Swarm) was launched in 2013 and it comprises a constellation of three identical satellites. The primary mission objective is analyzing and modeling the geomagnetic field and its temporal evolution, based ...

Long-term variations of the upper atmosphere parameters on Rome ionosonde observations and their interpretation

open access: yesJournal of Space Weather and Space Climate, 2017
A recently proposed self-consistent approach to the analysis of thermospheric and ionospheric long-term trends has been applied to Rome ionosonde summer noontime observations for the (1957–2015) period.

Impact of gravity wave drag on the thermospheric circulation: implementation of a nonlinear gravity wave parameterization in a whole-atmosphere model [PDF]

open access: yesAnnales Geophysicae, 2019
To investigate the effects of the gravity wave (GW) drag on the general circulation in the thermosphere, a nonlinear GW parameterization that estimates the GW drag in the whole-atmosphere system is implemented in a whole-atmosphere general circulation ...

Effects of Latitude-Dependent Gravity Wave Source Variations on the Middle and Upper Atmosphere

open access: yesFrontiers in Astronomy and Space Sciences, 2021
Atmospheric gravity waves (GWs) are generated in the lower atmosphere by various weather phenomena. They propagate upward, carry energy and momentum to higher altitudes, and appreciably influence the general circulation upon depositing them in the middle

The Effect of the Thermosphere on Ionosphere Outflows

open access: yesFrontiers in Astronomy and Space Sciences, 2021
The Naval Research Laboratory (NRL) Sami2 is Another Model of the Ionosphere (SAMI2) and Sami3 is Also a Model of the Ionosphere (SAMI3) ionosphere/plasmasphere codes have shown that thermosphere composition and winds significantly affect H+ outflows ...

Thermospheric targets [PDF]

open access: yesEos, Transactions American Geophysical Union, 2007
Recent decades have seen great progress in computer modeling of the global thermosphere‐ionosphere system. The models are derived by solving simultaneously the conservation equations of mass, momentum, and energy that govern the concentrations, velocities, and temperatures of the ions, electrons, and neutral gases.

Spatial and temporal correlations of thermospheric zonal winds from GOCE satellite observations

open access: yesFrontiers in Astronomy and Space Sciences, 2023
Winds in the thermosphere play an important role in the transport of momentum and energy in the upper atmosphere and affect the composition, dynamics and morphology of the ionospheric plasma.
