Longitudinal Variation of Thermospheric Density during Low Solar Activity from APOD Observations
Atmosphere, 2023 The longitudinal distribution of upper atmospheric density has been broadly studied. However, the studies mostly focused on 24 h averaged distribution.

Tidal signatures of the thermospheric mass density and zonal wind at midlatitude: CHAMP and GRACE observations [PDF]
Annales Geophysicae, 2015 By using the accelerometer measurements from CHAMP and GRACE satellites, the tidal signatures of the thermospheric mass density and zonal wind at midlatitudes have been analyzed in this study.

Sources of the High-Latitude Thermospheric Neutral Mass Density Variations [PDF]
Journal of Astronomy and Space Sciences, 2010 We investigate the sources of the variation of the high-latitude thermospheric neutral mass density depending on the interplanetary magnetic field (IMF) conditions.

An empirical model of the thermospheric mass density derived from CHAMP satellite [PDF]
Annales Geophysicae, 2018 In this study, we present an empirical model, named CH-Therm-2018, of the thermospheric mass density derived from 9-year (from August 2000 to July 2009) accelerometer measurements from the CHAllenging Mini-satellite Payload (CHAMP) satellite at ...

Thermospheric density structures over the polar regions observed with CHAMP [PDF]
Annales Geophysicae, 2005 Abstract. We report on the unexpected detection of considerable structure in high latitude thermospheric densities, as derived from an accelerometer onboard the CHAMP satellite. The width of the structures, which can either be maxima or minima, varies between a few hundred km and 2000 km. The amplitudes of these density extrema can reach 50% of ambient.

A Global Thermospheric Density Prediction Framework Based on a Deep Evidential Method
Space WeatherThermospheric density influences the atmospheric drag and is crucial for space missions. This paper introduces a global thermospheric density prediction framework based on a deep evidential method. The proposed framework predicts thermospheric density at
