Description

Researchers on this project operate two narrow-band, multi-frequency Doppler LiDARs at McMurdo Station. These LiDARs can make high-resolution observations of winds and temperatures in the middle and upper atmosphere. Simultaneous observations by the two instruments - a sodium LiDAR and an iron Boltzmann LiDAR - provide unprecedented levels of detail to characterize atmospheric conditions. The instruments have been hosted by Antarctica New Zealand (ANZ) in their Arrival Heights laboratory since late 2010. The observations provide critical data to address key science challenges associated with the space-atmosphere interaction region and, in particular, the sparsely observed high-latitude southern hemisphere.

Field Season Overview

For the summer 2023-24 season, LiDAR operations will be paused in October 2023 and restarted in February 2024 ahead of the winter 2024 season. For the pause, the equipment will be placed in a safe and secure standby state and monitored and tended to as needed by on-site support provided by ASC staff and other station staff (IT, station services, etc.). For winter 2024 operations, two science team members will winterover at McMurdo Station.
