A Study of the Diurnal Tide in the MLT Region During the 2020 Sudden Stratospheric Warming Over Yinchuan, China (38.8°N, 106.8°E)

Journal of Geophysical Research: Space Physics
We present a study of diurnal tidal variations in the mesosphere and lower thermosphere (MLT) region over Yinchuan (38.8°N, 106.8°E) during the 2020 Northern Hemisphere winter sudden stratospheric warming (SSW) event.

Vertical Structure of Terdiurnal Tides in the Antarctic MLT Region: 15‐Year Observation Over Syowa (69°S, 39°E)

Geophysical Research Letters, 2019
The terdiurnal tide (TDT) in the Antarctic mesosphere and lower thermosphere region is poorly known. This study examines TDT using neutral wind observations at Syowa during years of 2004–2018.

Manifestations of minor and final stratospheric warmings in the MLT and F2-region

23rd International Symposium on Atmospheric and Ocean Optics: Atmospheric Physics, 2017
We present the results of studying the state of the neutral upper atmosphere and the ionosphere over the Eastern Siberia region during minor winter sudden stratosphere warming (SSW) in early February, 2016 and final stratospheric warming in early March, 2016. We used the data from spectrometric measurements of OH (~87 km, 834.0 nm, (6-2)) and At O 2 (~

Wind measurements of MLT region using the Platteville, CO MEDAC 50MHz meteor radar

Journal of Atmospheric and Solar-Terrestrial Physics, 2005
Abstract Meteoroids enter the earth's atmosphere constantly, producing a trail of ions due to their interaction with the air molecules. Using radar techniques, these trails are detected and used as tracers of the atmospheric winds by measuring the Doppler shift of the return echo as the trails drift with the wind.

MATS satellite mission - observing gravity waves in the MLT region with tomographic limb imaging

MATS (Mesospheric airglow/Aerosol Tomography and Spectroscopy) is as Swedish satellite launched in November 2022. It observes O2 A-band airglow in near-infrared and UV light scattered from noctilucent clouds (NLCs) in limb imaging geometry and provides global 3-D temperature and NLC data products.
