Upper atmosphere physics data such as VLF, CNA, magnetic field and ULF have been continuously acquired by the MELCOM 70/25 computer system installed at Syowa Station, Antarctica in 1981. The original digital data are compiled using the M-180 computer system at the Information Processing Center, National Institute of Polar Research. The compilatory processes are divided into the following four steps; (1) Reproduction of the original tape in order to check the recording conditions, (2) Preservation of the original data by changing the recording density on the magnetic tape from 1600 BPI to 6250 BPI, (3) Compilation of the utility format tape from the original data, (4) Making the summary plots for all of the compiled data. These data are available to users on request.
