Supporting Stations: McMurdo Station
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
A new STAR Na Doppler LiDAR (A-123-M) will be installed in the Antarctic New Zealand Arrival Heights building, Laboratory C, adjacent to the existing Fe Boltzmann LiDAR (A-130-M). Team members will work on both projects for installation, refurbishment, data collection, maintenance, and training. The two LiDAR will run simultaneously and will require two over-wintering scientists, one from each LiDAR team, to support science requirements.
