On the relationship between auroral absorption, electrojet currents and plasma convection [PDF]
Annales Geophysicae, 2009 In this study, the relationship between auroral absorption, electrojet currents, and ionospheric plasma convection velocity is investigated using a series of new methods where temporal correlations are calculated and analysed for different events and ...

An investigation of latitudinal transitions in the SuperDARN Doppler spectral width parameter at different magnetic local times [PDF]
Annales Geophysicae, 2004 Latitudinal transitions from low to high Doppler spectral width in backscatter measured by the Super Dual Auroral Radar Network (SuperDARN) are now routinely used as proxies for the polar cap boundary (PCB) in the cusp-region ionosphere. In this paper

Suppressed migrating diurnal tides in the mesosphere and lower thermosphere region during El Niño in northern winter and its possible mechanism [PDF]
Atmospheric Chemistry and Physics, 2022 As observed by the Sounding of the Atmosphere using Broadband Emission Radiometry (SABER), the migrating diurnal tide (DW1) in the upper mesosphere and lower thermosphere (MLT) region decreased by ∼ 10 % during El Niño in the Northern Hemisphere (NH ...

Ground-based Observations for the Upper Atmosphere at King Sejong Station, Antarctica [PDF]
Journal of Astronomy and Space Sciences, 2014 Since the operation of the King Sejong Station (KSS) started in Antarctic Peninsula in 1989, there have been continuous efforts to perform the observation for the upper atmosphere. The observations during the initial period of the station include Fabry-

Statistical Study on Spatial Distribution of Frequency‐Chirping ECH Elements by Van Allen Probes
Geophysical Research Letters, 2023 Electron cyclotron harmonic (ECH) waves can scatter electrons into the atmosphere causing diffuse aurora with diffusion coefficients depending on the wave frequency. Here we report the Van Allen Probe observations of chirping ECH elements, which are fine
