Abstract This study combines 8 years of middle atmospheric wind data observed at 52°N latitude from two radars in different longitudinal sectors to investigate solar tides. The power spectral density of horizontal winds exhibits a −3 power law wit

Abstract Two ∼2‐week Ultra‐Fast Kelvin Wave (UFKW) events centered on days 158(203) during 2021 are investigated using winds, temperatures, plasma drifts and electron densities (Ne) measured by the Ionospheric CONnections (ICON) mission. Eastwa

Abstract First results are presented from the conjugate maneuvers performed by NASA's Ionospheric Connection Explorer (ICON) spacecraft. During each several‐minute maneuver, ICON crosses the magnetic equator, measuring the plasma drift at the ∼60

Rossby waves occur in rotating fluids. Here, the authors show observation of a Rossby wave second harmonic generation event in the middle atmosphere and confirm theoretically anticipated Rossby wave nonlinearity.

Introduction: The vertical coupling of the lower and upper atmosphere via atmospheric solar tides is very variable and affects the thermosphere and ionosphere system. In this study, we use Ionospheric Connection (ICON) explorer data from 220–270 Da

Abstract Retrieval of the properties of the middle and upper atmosphere can be performed using several different interferometric and photometric methods. The emission-shape and Doppler shift of both atomic and molecular emissions can be observed from

The concept of a global monsoon system collectively comprising 6 tropical regions is applied to Outgoing Longwave Radiation (OLR) as a proxy for convectively generated gravity waves (GWs), leading to the global monsoon convective system (GMCS). The s
