The Far Ultra Violet (FUV) ultraviolet imager onboard the NASA-ICON mission is dedicated to the observation and study of the ionosphere dynamics at mid and low latitudes. We compare O+ density profiles provided by the ICON FUV instrument du...
Isolated Peak of Oxygen Ion Fraction in the Post-Noon Equatorial F-Region: ICON and SAMI3/WACCM-X [0.03%]
午后赤道F区氧离子分数孤立峰：ICON和SAMI3/WACCM-X观测结果
Jaeheung Park,J D Huba,Roderick Heelis et al.
Jaeheung Park et al.
In the equatorial region, the fraction of oxygen ions (O+) in the topside ionosphere contains information on the source altitude of the plasma, which is controlled, in part, by the vertical plasma motion in the F-region. Previous studies on...
First results from the retrieved column O/N2 ratio from the Ionospheric Connection Explorer (ICON): Evidence of the impacts of nonmigrating tides [0.03%]
从电离层连接探测器(ICON)获取的O / N2 比率的初步结果：非迁移潮汐影响的证据

Scott L England et al.
In near-Earth space, variations in thermospheric composition have important implications for thermosphere-ionosphere coupling. The ratio of O to N2 is often measured using far-UV airglow observations. Taking such airglow observations from s...
Atmosphere-Ionosphere (A-I) Coupling as Viewed by ICON: Day-to-Day Variability Due to Planetary Wave (PW)-Tide Interactions [0.03%]

Coincident Ionospheric Connections Explorer (ICON) measurements of neutral winds, plasma drifts and total ion densities (:=Ne, electron density) are analyzed during January 1-21, 2020 to reveal the relationship between neutral winds and ion...
Multi-Instrument Characterization of Magnetospheric Cold Plasma Dynamics in the June 22, 2015 Geomagnetic Storm [0.03%]
多仪器表征地磁暴期间磁层冷等离子体动力学：以2015年6月22日的地磁暴为例

We present a comparison of magnetospheric plasma mass/electron density observations during an 11-day interval which includes the geomagnetic storm of June 22, 2015. For this study we used: Equatorial plasma mass density derived from geomagn...
Geospace Plume and Its Impact on Dayside Magnetopause Reconnection Rate [0.03%]
地空间冕物质抛射(plume)及其对白昼磁层顶重新连接率的影响研究
Ying Zou,Brian M Walsh,Xueling Shi et al.
Ying Zou et al.
The role a geospace plume in influencing the efficiency of magnetopause reconnection is an open question with two contrasting theories being debated. A local-control theory suggests that a plume decreases both local and global reconnection ...
Plasma Turbulence at Comet 67P/Churyumov-Gerasimenko: Rosetta Observations [0.03%]

We perform a power spectral analysis of magnetic field fluctuations measured by the Rosetta spacecraft's magnetometer at comet 67P/Churyumov-Gerasimenko. We interpret the power spectral signatures in terms of plasma turbulent processes and ...
Ion Velocity and Temperature Variation Around Topside Nighttime Irregularities: Contrast Between Low- and Mid-Latitude Regions [0.03%]
