Abstract For the first time, we measured ellipticity of direct Rayleigh waves at intermediate periods (15–35 s) on Mars using recordings three large seismic Martian events, including S1222a, largest event recorded by InSight mission. These measurements, together with P‐to‐s receiver functions and P‐wave reflection times, were utilized for performing a joint inversion local crustal structure lan...

S U M M A R Y We calculate two-station phase measurements using single-station measurements made on USArray Transportable Array data for surface waves at periods from 25 to 100 s. The phase measurements are inverted for baseline Love and Rayleigh wave phase velocity maps on a 0.5◦ × 0.5◦ grid. We make estimates of the arrival angle for each event at each station using a mini array method simila...

Rayleigh and Raman scatter measurements from The University of Western Ontario Purple Crow Lidar (PCL) have been used to develop temperature climatologies for the stratosphere, mesosphere, and thermosphere using data from 1994 to 2013 (Rayleigh system) and from 1999 to 2013 (vibrational Raman system). Temperature retrievals from Rayleigh-scattering lidar measurements have been performed using t...
