The coordinated observations of the Antarctic middle atmosphere were conducted by the wintering parties of the 23rd-26th Japanese Antarctic Research Expeditions at Syowa Station (69.0°S, 36.6°E) during 1982-1985 in cooperation with the Middle Atmosphere Program (MAP). The wintering party of JARE-26 carried out the final campaign for the MAP at Syowa Station. The middle atmosphere was observed with a combination of remote-sensing techniques from the ground and spacecraft and in-situ measurements on balloons and sounding rockets. The major ground-based remote-sensing facilities were a Dobson spectrophotometer for ozone measurement, a ruby lidar for stratospheric aerosol measurement and a dye lidar for sodium layer measurement, a VHF doppler radar for measuring motions of ionized and neutral atmospheres and a multi-beam riometer for monitoring particle precipitation. The meteorological rockets launched at 2-hour intervals succeeded in detecting internal gravity waves at the 20-70km altitude range. This paper gives an outline of the MAP campaign in 1985.
