2016-2017 USAP Field Season
High-resolution Na Doppler LiDAR observations of the middle and upper atmosphere at McMurdo, Antarctica
Dr. Xinzhao Chu
University of Colorado Boulder
Supporting Stations: McMurdo Station
The project will deploy a narrowband, three-frequency Na (Sodium) Doppler LiDAR to McMurdo Station that is capable of measuring both winds and temperatures vertically. This LiDAR will make high-resolution observations of the middle and upper atmosphere and simultaneous observations with the co-located Fe Boltzmann LiDAR, which has been hosted by Antarctica New Zealand (ANZ) in their Arrival Heights building since late 2010. The Na Doppler observations will provide critical data to address key science challenges associated with the space-atmosphere interaction region.
Field Season Overview
This season, the team will make modifications to Antarctica New Zealand's Lab C at Arrival Heights to prepare for the Student Training and Atmospheric Research (STAR) Na Doppler LiDAR deployment in the 2017-18 season. The work on Lab C will include: adding electrical power, making modifications to accommodate the STAR Na Doppler LiDAR telescope hatch and outgoing laser beam, and adding an HVAC system for heat dissipation and room temperature stabilization. The team will also address electromagnetic interference (EMI) issues with the laser transmitter installation using RF filters, as was done for the existing Fe Boltzmann LiDAR.
