Research Locations: Arrival Heights / ARO
This project continues long-term observation, characterization, and understanding of high-latitude atmospheric motions, in particular mesospheric motions and thermospheric persistent vertical winds near Arrival Heights and simultaneously with those at South Pole and Mount John, NZ. Wintertime mesospheric kinetic temperature observations have shown the presence of dynamical coupling between the stratosphere and the upper regions of the atmosphere in the Southern Hemisphere. Results indicate that the dynamical processes leading to the stratospheric warming or cooling are already in place during the austral winter and the early mesospheric signals lead to the potential capability to estimate the springtime ozone hole.
Field Season Overview:
The major activities are the observational phase during the austral winter and calibration during the rest of the year. Year-round support is provided by the staff Research Associates (RA) at McMurdo and South Pole Stations. Four participants will deploy during the austral summer to maintain, repair, and calibrate the equipment as needed.
