A system science perspective of the drivers of equatorial plasma bubbles
Frontiers in Astronomy and Space Sciences, 2023 The complex drivers of equatorial plasma bubbles and resulting scintillation requires a system science approach spanning the Magnetosphere-Ionosphere-Thermosphere-Mesosphere disciplines.

Eos, 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.

Thermospheric tides during thermosphere mapping study periods [PDF]
Advances in Space Research, 1987 Neutral exospheric temperatures at 53°, 43° and 33° latitude from Millstone Hill steerable-antenna Thomson scatter measurements, and at 19° latitude from the Arecibo Observatory, obtained during three Thermosphere Mapping Study (TMS) coordinated campaign intervals during 1984 and 1985. are analyzed for diurnal and semidiurnal tidal components.

Martian Thermospheric Warming Associated With the Planet Encircling Dust Event of 2018
Geophysical Research Letters, 2020 We report the first observations of Martian thermospheric warming associated with the Planet Encircling Dust Event (PEDE) of 2018. We used dayglow observations made by the Imaging Ultraviolet Spectrograph instrument aboard the MAVEN spacecraft to ...

Effects of a mid-latitude solar eclipse on the thermosphere and ionosphere - A modelling study
, 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 ...

New perspectives on thermosphere tides: 2. Penetration to the upper thermosphere [PDF]
Earth, Planets and Space, 2014 In this paper, we present new multi-year and 72-day mean seasonal-latitudinal tidal structures in exospheric temperature derived from joint analysis of CHAMP and GRACE accelerometer measurements. These results include diurnal tides DE3, DE2, D0, and DW2 and semidiurnal tides S0, SE1, SE2, SE3, SW4, and SW6.

Numerical modeling of spatial perturbations of the ionosphere from local tropospheric sources
Solar-Terrestrial PhysicsThe paper presents the results of modeling of spatial and temporal perturbations of the thermosphere during a strong meteorological disturbance. The modeling was performed using the Global Self-Consistent Model of the thermosphere, ionosphere, and ...
