This project continues the operation of the Fe Boltzmann LiDAR instrument installed in the Antarctica New Zealand (ANZ) lab at Arrival Heights. Primary research objectives are to acquire vertical profiles of atmospheric temperature (30–155 kilometers), Fe (iron) density (70–155 kilometers), and polar mesospheric cloud (PMC), to study the chemistry and dynamics of the polar atmosphere and to establish the baseline temperature, Fe, PMC, and gravity-wave climatologies.
Field Season Overview
This is the fitth season in the renewal period and the overall eighth season for the Fe Boltzmann LiDAR campaign at Arrival Heights. Team members will continue to operate and maintain the Fe Boltzmann LiDAR year around. Each summer season, the project team will participate in the LiDAR operation to help achieve multiple days of continuous LiDAR observations. A new STAR Na Doppler LiDAR for project A-123-M will be deployed in November 2017. For that reason, one of the major goals of A-130-M this season is to acquire simultaneous Fe LiDAR and Na LiDAR data as much as possible for the science goals proposed for both projects. Two team scientists will overwinter in the year of 2018 to operate and maintain the two LiDAR systems. The team will travel daily between McMurdo and Arrival Heights. Activities this season include: (1) Continuing data collection; (2) Refurbishing, maintaining and upgrading the LiDAR system to its optimum status; (3) Upgrading the LiDAR computer, data acquisition system, and wavelength control programs; (4) Training several new LiDAR operators.
