Geospace is populated by plasma that mostly originates from the solar wind. Interaction of these two major players - geomagnetic field and solar wind plasma produces many electromagnetic phenomena such as beautiful ionospheric aurorae (Northern and Southern lights), natural electromagnetic radiation, field-aligned and ionospheric currents, that prominently appear and are observed in the polar areas where they are most intense. Natural radio emissions are important in a broad range of space plasma physics because they provide a means of remotely sensing plasma conditions and processes, and in some cases, they control energy flows or determine boundaries and energy exchange in space plasmas. Auroral radio emissions arise from the same processes that produce emissions in magnetospheric, planetary, and astrophysical environments, and therefore comprise a laboratory for studying those processes. This award will study the Auroral Kilometric Radiation (AKR) observed by distant satellites and ground-level AKR-like signals, as well as the relationship between escaping and leaked AKR, as well as the other types of auroral radio emissions, via simultaneous high-resolution wave measurements at South Pole and from satellites carrying high-resolution wave receivers in the appropriate frequency range. One of the main science objectives is to confirm a direct connection or lack thereof between escaping AKR observed by satellites and leaked AKR observed at South Pole. Such a connection would imply a new radiative mechanism of the cyclotron maser mechanism, which plays a major role in many space-plasma environments and would open new methods of remotely sensing the auroral acceleration region from ground level. These investigations require Antarctic observations, most obviously for the conjugate studies but also for study of leaked AKR which cannot be observed at northern hemisphere locations due to radio frequency interference. This project will incorporate its research and engineering aspects into introductory courses to large numbers of pre-engineering and physics undergraduates.

The Geospace environment comprises a complex system of the incoming solar wind plasma flow interacting with the Earth\u0027s magnetic field and transferring its energy and momentum into the magnetosphere. This interaction takes place mainly on the Earth\u0027s dayside, where reconnecting geomagnetic field line might be \"open\" and directly connected to the interplanetary magnetic field lines, thus providing direct pathways for the solar wind energy to be transferred down to the ionosphere and upper atmosphere. The spatial extent of the polar cap areas controlled by the ionospheric plasma convection demarcate the so-called \"Open-Closed Boundary\" where solar wind particles reach down polar ionospheres. Observations of that boundary serve the important role in validating geomagnetic field modeling and help studying space weather. Motivated by the compelling Geospace research in the polar regions, this award will allow scientists to investigate magnetosphere-ionosphere coupling processes and ionospheric irregularities inside the polar caps and their space weather impacts by establishing a new ground-based network that will be deployed in the Antarctic polar cap region. This will be achieved using three new instrumented platforms (next generation of Automatic Geophysical Observatories) along the snow traverse route from the Korean Antarctic Station Jang Bogo toward to the Concordia Station at Dome C by the Korea Polar Research Institute\u0027s (KOPRI) team. Geospace data collected by these three platforms will be shared by the U.S. and Korean researchers, as well as will be made available to other scientists. The research involves early-career researchers, as well as train students who will build and operate remote Antarctic platforms, as well as analyze collected data to investigate space weather events and validate models. This project expands the U.S. institutions partnership with the KOPRI scientists and logistical support personnel.

These physical processes take place mainly on the Earth\u0027s dayside, diverting most of the energy along geomagnetic field lines toward both the northern and southern polar regions. Understanding this complex interaction process that couples both polar ionospheres is important for developing the physical models that can describe and predict space weather disturbances and help mitigate their impacts on humans\u0027 technological systems - from near-Earth space assets down to electrical grids and long pipelines. There is a strong need to collect sufficient geophysical data to investigate the above-mentioned processes, particularly from the southern hemisphere. With this award, the grantees will build and deploy additional ground-based observations platforms in the East Antarctic Plateau, enhancing capabilities of the existing meridional array of already deployed autonomous, low-powered magnetometers. This will make the southern array of magnetometers two-dimensional and geomagnetically conjugate to similar instruments deployed in Greenland and Svalbard, thus making possible a global view of the magnetospheric regions where natural, ultra-low frequency electromagnetic waves are generated. The project involves young scientists who will operate remote Antarctic magnetometers and analyze collected data to investigate space weather events and validate models.
