Mesoscale observations of Joule heating near an auroral arc and ion-neutral collision frequency in the polar cap E region [PDF]
, 2011 We report on the first mesoscale combined ionospheric and thermospheric observations, partly in the vicinity of an auroral arc, from Svalbard in the polar cap on 2 February 2010. The EISCAT Svalbard radar employed a novel scanning mode in order to obtain

Climatology of TEC Longitudinal Difference in Middle Latitudes of East Asia
Remote Sensing, 2022 In this paper, a statistical analysis of the diurnal, seasonal and solar cycle variation in the TEC longitudinal difference in midlatitudes of East Asia is presented using CODE GIMs data in 2015–2019. Moreover, the empirical neutral wind model HWM-14 and

Spatial and temporal correlations of thermospheric zonal winds from GOCE satellite observations
Frontiers in Astronomy and Space Sciences, 2023 Winds in the thermosphere play an important role in the transport of momentum and energy in the upper atmosphere and affect the composition, dynamics and morphology of the ionospheric plasma.

Wind-tunnel simulations of wind-turbine arrays in neutral and non-neutral winds
Journal of Physics: Conference Series, 2014 Wind tunnel simulations have been made of a neutral atmospheric boundary layer (ABL), a stable layer and an unstable layer, typical of offshore conditions, in order to better understand wake development and turbine-wake interactions. Measurements of the wake of a single turbine showed a slower reduction of the velocity deficit for the stable case, and ...

Longitudinal variability of thermospheric zonal winds near dawn and dusk
Frontiers in Astronomy and Space Sciences, 2023 Understanding the morphology and dynamics of the thermosphere is key to understanding the Earth’s upper atmosphere as a whole. Thermospheric winds play an important role in this process by transporting momentum and energy and affecting the composition ...
