The Wind Imaging Interferometer (WINDII) was launched on the NASA's Upper Atmosphere
Research Satellite on 12 September 1991 and operated until 2003. Its role in the mission …

A stratospheric sudden warming episode was self‐consistently generated in the coupled
National Center for Atmospheric Research Thermosphere, Ionosphere, Mesosphere, and …

The recently launched Global‐scale Observations of the Limb and Disk (GOLD) Mission
observed prominent quasi‐16‐day oscillations (Q16DOs) in the OI 135.6‐nm nightglow from …

It is well known that solar EUV and UV forcing and auroral heat and momentum sources
have a significant effect on thermospheric and ionospheric structure and dynamics. Yet the …

[4] In the beginning, we present some examples of Q disturbances to get an idea of how they
look in comparison with usual F2-layer storm effects. A strong daytime negative disturbance …

In the middle atmosphere, spring transition is the time period where the zonal circulation
reverses from winter westerly to summer easterly which has a strong impact on the vertical …

We present a study of the semidiurnal solar tide (S2) during the fall and spring transition
times in the Northern Hemisphere. The tides have been obtained from wind measurements …

The observed NmF2 and NmE variations were analyzed for the periods of positive and
negative quiet-time F2-layer disturbances (Q-disturbances) observed in the midlatitude …

The interannual variability of the springtime transition date of the stratospheric circulation is
analyzed on the basis of the data assimilated in the UK Met Office and NCEP/NCAR models …

Airglow observations with a Spectral Airglow Temperature Imager (SATI), installed at the
Sierra Nevada Observatory (37.06° N, 3.38° W) at 2900-m height, have been used to …
