Abstract: An Autonomous Adaptive Low-Power Instrument Platform (AAL-PIP) Chain of six stations has been newly established on East Antarctic Plateau along the 40 degree geomagnetic meridian, to investigate interhemispheric geomagnetically conjugate current systems, waves, and other space weather phenomena in Polar Regions. These six stations, PG0 to PG5, which host low-power magnetometers (Fluxgate and Searchcoil), dual frequency GPS receivers, HF radio experiment, and run autonomously with solar power and two-way satellite communication, are designated at the geomagnetically conjugate (based on the International Geomagnetic Reference Field) locations of the West Greenland geomagnetic chain covering magnetic latitudes from 70° to 80°. We present the development, deployment, and operation of this chain, as well as the data collected by the chain and some preliminary scientific results showing evidence of interhemispheric asymmetries, which are important to better understand Solar Wind - Magnetosphere - Ionosphere (SWMI) coupling in Polar Regions. Recent investigations focus on magnetic impulse (MI) events, traveling convection vortices (TCVs), and ultra-low frequency (ULF) waves in the coupled southern and northern hemispheres.
