Researchers on this project deployed a narrow-band, three-frequency Na (Sodium) Doppler LiDAR to McMurdo Station that is capable of measuring both winds and temperatures vertically. This LiDAR makes high-resolution observations of the middle and upper atmosphere together with simultaneous observations of the co-located Fe Boltzmann LiDAR. Both instruments are hosted by the Antarctica New Zealand (ANZ) program in their Arrival Heights building since late 2010. The Na Doppler observations provide critical data to address key science challenges associated with the space-atmosphere interaction region.

Field Season Overview

Observations with the STAR Na Doppler LiDAR started in January 2018 and continue through the entire year including over the austral winter. Researchers also continue simultaneous observations with the Fe LiDAR (A-130-M) at Arrival Heights while finishing optimization of the Na lidar and upgrading the Fe LiDAR, as well as trainings new winter and summer students. Students will conduct data analysis and progress toward the completion of their graduate degrees.
