The Polar Patrol Balloon (PPB#6) was launched from Syowa Station, Antarctica by the 34th Japanese Antarctic Research Expedition on 5th January 1993. The detection system for hard X-rays and Protons were carried with the purpose of research for the elemental and composition of cosmic rays, solar energetic particles, cosmic gamma ray bursts and auroral x-rays. The PPB#6 moved westward by 1.5 circumpolar rounds over Antarctica. This paper presents the variation of atmospheric hard x-rays with the balloon altitudes in the whole Antarctica.
