Residuals to the CHAOS‐6 Geomagnetic Field Model Caused by Magnetospheric Currents During Enhanced Magnetic Activity

Publikováno v: Geochemistry, Geophysics, Geosystems, Vol 21, Iss 6, Pp n/a-n/a (2020)

Abstract Thanks to mapping missions, like Ørsted, CHAMP, and Swarm, we have gained a detailed understanding of the geomagnetic field. High‐resolution models like POMME, GRIMM, or CHAOS are able to describe the main parts of the Earth's magnetic fi

In this study we performed a detailed analysis on the scale-size of field-aligned currents (FACs) at auroral latitudes, using the well-calibrated magnetic data from the non-dedicated magnetic field mission, Gravity Recovery and Climate Experiment Fol

Short‐Term Variability of Equatorial Electrojet Modulation by Solar Tidal and Planetary Waves, as Derived From the Swarm Constellation

Autor: Patrick Alken, Hermann Lühr, Yun-Liang Zhou

Publikováno v: Journal of Geophysical Research: Space Physics

ESA’s constellation mission Swarm with its three identical spacecraft allows the separation of spatial and temporal variations of wave phenomena. Here we investigate the modulation of the equatorial electrojet (EEJ) amplitude by solar tides and pla

Relation between the asymmetric ring current effect and the anti-sunward auroral currents, as deduced from CHAMP observations

Autor: Hermann Lühr, Yun-Liang Zhou

Publikováno v: Annales Geophysicae
Annales Geophysicae, Vol 38, Pp 749-764 (2020)

During magnetically active periods the storm-time disturbance signal on ground develops commonly an azimuthal asymmetry. Negative deflections of the magnetic horizontal (H) component are enhanced in the 18:00 local time sector and smallest in the mor

Average ionospheric mid‐ and low‐latitude night‐time zonal currents deduced from CHAMP

Autor: Yun-Liang Zhou, Patrick Alken, Hermann Lühr

Publikováno v: Journal of Geophysical Research: Space Physics

By utilizing magnetic field measurements collected by CHAMP during the years 2001‐2009, average characteristics of night‐time ionospheric zonal currents at middle and low latitudes are investigated. We provide for the first time the detailed depe

Diurnal evolution of the F region electron density local time gradient at low and middle latitudes resolved by the Swarm constellation

Autor: Chao Xiong, Yun-Liang Zhou, S. Y. Ma, Hermann Lühr

Publikováno v: Journal of Geophysical Research

In this study we have provided new insights into the local time gradient of F-region electron density (ΔNe) derived from the lower pair of Swarm satellites flying side-by-side. Our result shows that the electron density (Ne) increase starts just at
