An Investigation of the Variability of Tides in the Upper Mesosphere (Meteor Radar)
A computer simulation of the Urbana, Illinois, meteor radar is performed to estimate the accuracy of the data analysis procedures in determining upper mesospheric tides. Various wind models such as planetary waves, gravity waves, and turbulence are tested and it is found that for reasonable values …

Lidar and Modeling Studies of the Mesospheric Iron and Sodium Layers
… metals are believed to be the product of meteoric ablation. Very thin and brief layers observed in our lidar data, attributed to recently ablated meteors, are used to examine this hypothesis. The altitude distribution of these trails is compared to a model of meteoric deposition, meteor …

Investigation of the Winds and Electron Concentration Variability in the D Region of the Ionosphere by the Partial-Reflection Radar Technique
… technique to study the possible meteorological causes of the winter anomaly in the mesosphere at midlatitudes. Winds data obtained by the meteor-radar experiment at Urbana are also compared with electron concentration data measured at Urbana. A significant correlation is shown in …

On the Interaction between Gravity Waves and Atmospheric Thermal Tides
… Fire Optical Range (SOR, 35_N, 106.5_W) and a meteor radar data at the Andes LIDAR Observatory (ALO, 30.3_S, 70.7_W). At SOR, the gravity waves are shown to enhance or damp the amplitude of the diurnal variations dependent on altitude while the phase is always delayed. The results compare well …

Studies of gravity wave and thermal tide and their interactions in the middle atmosphere
… (MLT) over Maui, HI is investigated using the meteor radar horizontal wind measurement from years 2002 to 2007. The semiannual oscillation (SAO) of tidal amplitudes is dominant above 88 km, with amplitudes at the equinoxes 2-3 times larger than at the solstices. Below 88 km, the annual …

Role of Planetary Wave-Tide-Gravity Wave Interactions In Whole Atmosphere Coupling
… events. The development of a new multi-static meteor radar at 30ºS, named Chilean Observation Network De MeteOr Radars (CONDOR), provides a key dataset for the present studies. Wind validation of this new radar system is performed across different sites and compared to a co-located sodium …
