Studies of the polar Ionosphere and Magnetosphere from measurements in Antarctica

Project Description:
Since the advent of space flight, it has become increasingly important to understand the Earth’s space environment. The Polar Regions, and especially Antarctica, play a crucial role in this research. The Antarctic is magnetically connected to vast regions of the magnetosphere and solar wind, and provides the only practical locations for Earth-based measurements at the highest magnetic latitudes. At lower magnetic latitudes, Antarctic observatories are essential for efforts to understand global processes occurring in conjugate ionospheres. This collaborative project will continue studies of the polar ionosphere and magnetosphere from South Pole and McMurdo Stations. Magnetometer observations, high frequency (HF) cosmic noise absorption measurements (riometry) and auroral luminosity measurements will form the basis of these investigations, and will include collaboration with other investigators using complementary data sets. Specifically, this project maintains and operates magnetometers at South Pole and McMurdo stations, as well as imaging and broadbeam riometers and 2-wavelength zenith photometers. Researchers also provide and operate the data acquisition systems at South Pole and McMurdo for the common recording of other geophysical data and the provision of these data to all investigators.

Field Season Overview:
The magnetometer, riometer and photometer systems at both McMurdo and South Pole continuously collect data. Acquisition is provided via a common data recording system at both locations. The contract Research Associates (RAs) at each station supports the equipment year-round. This year project team members will visit McMurdo to upgrade hardware and software. At the South Pole, the Stanford VLF receiver that was previously maintained under this project is now maintained by LaBelle (A-125-S).
