Thermospheric mass densities are investigated to explore their responses solar irradiance and geomagnetic activity during the period from 31 October 7 November 2021. Utilizing data Global Navigation Satellite System (GNSS) payload an ionization gauge mounted on Orbital Neutral Atmospheric Detector (OAD) onboard QQ-Satellite, thermospheric derived through two independent means: precise orbit determination (POD) pressure measurements. For first time, observations of these techniques compared...
The Meridian Project’s sounding rocket mission uses a mass spectrometer to conduct in-situ atmospheric detection. In order assess the influence of surface material outgassing and attitude control jet on spectrometer’s detection, platform was modeled simulated. Using physical field simulation software COMSOL Monte Carlo method, this study investigated whether gas molecules from two cases could enter sensor sampling port after colliding with background atmosphere. results show that detection...
In this article, high spatiotemporal resolution data obtained by the atmospheric density detector carried China’s APOD satellite are used to study hemispheric asymmetry of thermospheric density. A detailed analysis is first performed on dual magnetic storm event that occurred near autumnal equinox 8 September 2017. The results show enhancement ratio in southern polar region (SPR) duskside was approximately 1.33–1.65 times northern (NPR), demonstrating a strong response during storm. However,...
The response of thermosphere density to geomagnetic storms is a complicated physical process. Multi-satellite joint observations at the same altitude but different local times (LTs) are important for understanding this process; however, until now such studies have hardly been done. In report, we analyze in detail mass 510 km during April 23−24, 2023 storm using data derived from TM-1 satellite constellation and Swarm-B satellites. show that there were significant LT differences hemispheric...
