Special issue}, month = {Sep}, note = {P(論文), The first Japanese scientific balloon experiment at Esrange, Kiruna, Sweden was carried out on September 10 and 11,1980,in order to obtain vertical profiles of X-ray intensity, ozone density, and VLF wave spectrum intensity at a northern high-latitude. Since there were very quiet geomagnetic conditions for two balloon flights, observational results reveal a typical quiet time X-ray intensity profile and an ozone vertical profile in the high-latitude autumn. No evident VLF emissions associated with an auroral activity were observed, except for noises of power line radiation and lightning noises from Africa. Ground-based observations of the three components of geomagnetic field, cosmic noise absorption, pulsations and VLF waves were made in conjunction with the one month campaign and the data corresponding to several substorms were analyzed and compared with observations at the Syowa Station, Antarctica.}, pages = {155--172}, title = {X-ray intensity, ozone density, and VLF wave intensity observed by scientific balloon experiments at Esrange}, volume = {22}, year = {1982} }
