Trends in the Airglow Temperatures in the MLT Region—Part 1: Model Simulations [PDF]
Atmosphere, 2020 Airglow intensity-weighted temperature variations induced by the CO2 increase, solar cycle variation (F10.7 as a proxy) and geomagnetic activity (Ap index as a proxy) in the Mesosphere and Lower Thermosphere (MLT) region were simulated to quantitatively ...

Meteor Radar for Investigation of the MLT Region: A Review
AtmosphereThis is an introductory review of modern meteor radar and its application to the measurement of the dynamical parameters of the Mesosphere Lower Thermosphere (MLT) Region within the altitude range of around 70 to 110 km, which is where most meteors are ...

Observation of MLT region winds and tides by the USTC Mengcheng meteor radar
JUSTC, 2023 The atmospheric winds and waves in the mesosphere and lower thermosphere (MLT) region are essential for studying the dynamics and climate in the middle and upper atmosphere. The University of Science and Technology of China (USTC) meteor radar located at

Ionospheric response to the ultrafast Kelvin wave in the MLT region [PDF]
Journal of Geophysical Research: Space Physics, 2014 AbstractThe modulation of the ultrafast Kelvin wave (UFKW) on the equatorial ionosphere is investigated, using satellite neutral wind and temperature observations in the mesosphere/lower thermosphere (MLT) and ground‐based global maps of total electron content (TEC) observations.

Gravity wave momentum fluxes from MF and meteor radar measurements in the polar MLT region [PDF]
Journal of Geophysical Research: Space Physics, 2014 AbstractAnnual cycles of horizontal winds and gravity wave (GW) momentum fluxes in the mesosphere/lower thermosphere (MLT) are presented for the medium frequency Doppler radar at Saura (SMF radar, located at 69°N, 16°E) for the first time. Four year mean wind and momentum flux fields for 2008 through 2011 clearly show the coupling and interactions ...

Impact of sudden stratospheric warmings on the neutral density, temperature and wind in the MLT region [PDF]
Frontiers in Astronomy and Space Sciences, 2023 In this study, the neutral density and horizontal wind observed by the four meteor radars, as well as the temperature measured by the Microwave Limb Sounder (MLS) onboard the Aura satellite are used to examine the response of neutral density, wind, and ...

An investigation of latitudinal transitions in the SuperDARN Doppler spectral width parameter at different magnetic local times [PDF]
Annales Geophysicae, 2004 Latitudinal transitions from low to high Doppler spectral width in backscatter measured by the Super Dual Auroral Radar Network (SuperDARN) are now routinely used as proxies for the polar cap boundary (PCB) in the cusp-region ionosphere. In this paper
