The field intensity deduced from those computed results is discussed in comparison with that measured on board the ship of the Japanese Antarctic Research Expeditions as already reported in Parts I and II of this paper. It is confirmed quantitatively to a certain degree that the ionization in the nighttime E region is responsible for the absorption of MF and lower HF waves.}, pages = {9--23}, title = {夜間の電離層吸収 : III.夜間電離層に入射する中短波電波の通路と吸収(日本南極地域観測隊の報告)}, volume = {41}, year = {1971}, yomi = {ワカイ, ノボル} }
