The proposal that a multi-national astrophysical observatory be established on the highest area of the Antarctic ice plateau (Dome A) has centred on the opportunities for optical, infra-red and submm wave astronomy. Such a site could also be used to extend the world-wide cosmic ray observatory network. Suitable cosmic ray experiments for the site are considered. Additionally, possible geomagnetic and upper atmospheric physics measurements from such a site are briefly discussed. 32.1 INTRODUCTION The Dome A site on the Antarctic ice plateau is located at 67E, 82.4S at an altitude of 4270 m. The pressure altitude is even higher, exceeding 5000 m. The location has many unique features which make it a desirable site for cosmic ray observations. A large IQSY neutron monitor at Dome A would be the highest monitor in the world and would have the lowest energy cutoff (both atmospheric and geomagnetic) of any such monitor. This would be invaluable in the study of Ground Level Enhancements (GL.
