TL;DR: In this article, the authors derived a new technique for determining the height of a constant density surface at altitudes of 78-85 km from a decade of observations by a meteor radar located at Davis Station in Antarctica and compared with observations from the Microwave Limb Sounder instrument aboard the Aura satellite.

TL;DR: In this paper, a spectral based technique is developed allowing the transform to be applied at low temporal sampling rates, and simulations are used to compare meteoroid speeds determined using the Fresnel transform and alternative techniques, confirming that the Fourier transform produces the most accurate meteoroid speed estimates for high effective pulse repetition frequencies.

TL;DR: In this paper, a VHF atmospheric radar (wind profiler) was used to study tropospheric winds during the Darwin Area Wave Experiment (DAWEX), which operated at a frequency of 54.1 MHz.

TL;DR: In this article, partial reflection differential absorption and differential phase observations have been used to systematically study collision frequencies (ν) in D-region of the lower ionosphere, and observations made with the large MF radar located at Buckland Park (35° S, 138° E ) near Adelaide in the period September 1996-December 2000 show ν values larger than predicted by previously used models.

TL;DR: In this paper, the decay time of meteor radar echoes is determined by temperature and pressure, and it is suggested that absorbing aerosols can both decrease and increase the decay times of radar echoes, depending on meteor, atmospheric, and radar parameters.
