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 (Na) LiDAR and an iron (Fe) Boltzmann LiDAR - provide unprecedented levels of detail to characterize atmospheric conditions. The instruments have been hosted by the Antarctica New Zealand (ANZ) program 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 in the sparsely observed high-latitude southern hemisphere.


Field Season Overview

Six participants will deploy to conduct observations with the Na Doppler and Fe Boltzmann LiDARs. They will upgrade, refurbish, and perform routine maintenance on the instruments. They will also train students who will analyze data and progress toward completing their graduate degrees.
