Effects of atmospheric oscillations on the field-aligned ion motions in the polar F-region [PDF]
Annales Geophysicae, 2000 The field-aligned neutral oscillations in the F-region (altitudes between 165 and 275 km) were compared using data obtained simultaneously with two independent instruments: the European Incoherent Scatter (EISCAT) UHF radar and a scanning Fabry-Perot ...

Evaluation of Blended Wind Products and Their Implications for Offshore Wind Power Estimation
Remote Sensing, 2023 The Cross-Calibrated Multi-Platform (CCMP) wind analysis is a satellite-based blended wind product produced using a two-dimensional variational method. The current version available publicly is Version 2 (CCMP2.0), which includes buoy winds in addition ...

Influence of Scattered Sunlight for Wind Measurements with the O2(a1Δg) Dayglow
Remote Sensing, 2022 Observing the O2(a1Δg) dayglow with the limb-viewing DASH instrument enables remote sensing of neutral wind in near space. Many advantages are gained by using this new approach, but the influence factors on measurement accuracy have not been thoroughly ...

Responses of the wintertime auroral E-region neutral wind to varying levels of geomagnetic activity
Frontiers in Astronomy and Space Sciences, 2023 Introduction: The auroral E-region is an important interface where forces from the magnetosphere and the lower atmosphere converge and have a significant effect on the vertical structure of the neutral winds. The resulting vertical neutral wind structure

Explaining Ionospheric Ion Upflow in the Subauroral Polarization Streams
Remote Sensing, 2022 Ionospheric ion upflow is an important process for magnetosphere-ionosphere coupling via O+ source for the magnetosphere. This process occurs frequently in the subauroral polarization stream (SAPS) region where the SAPS-enhanced ion-neutral frictional ...

Neutral winds from mesosphere to thermosphere—past, present, and future outlook
Frontiers in Astronomy and Space Sciences, 2023 The Earth’s upper atmosphere (85–550 km) is the nearest region of geospace and is highly dynamic in nature. Neutral winds impact a large portion of the dynamics in this region.
