2019-2020 USAP Field Season
Lower thermospheric science using new meteor radar at McMurdo Station
Dr. Scott Palo
Supporting Stations: McMurdo Station
This project will observe the mesosphere and lower thermosphere (MLT) between 80 and 120 kilometers above the earth. This is a highly dynamic region that couples the lower terrestrial atmosphere with the upper atmosphere near-earth space environment. Of particular importance in this region are both the upward propagating thermally forced atmospheric tides, global-scale planetary waves, and small-scale gravity waves. All these phenomena transport heat and momentum from the lower atmosphere into the upper atmosphere. The primary goal of this research is to observe, quantify, model, and further understand the spatial-temporal structure and variability of the MLT circulation above Antarctica.
Field Season Overview
Two to three team members will arrive on station in late January and stay for approximately two weeks. They will travel to the radar site to upgrade system software, make a full inspection of the system and grounds, and collect and replace archival data disks. The experiment runs year around. An on-site research associate provides weekly support throughout the year.
