 note = {The altitude intensity profile of the MF radio wave transmitted from Kumamoto was observed by the sounding rocket S-310-18. An electron density profile in the D region was estimated by comparing the observed value with the MF radio wave absorption calculated by the generalized full wave method when the collision frequency is proportional to an atmospheric pressure. The obtained electron density profile showed a distinct peak at an altitude of 72km and showed an almost constant value of 600(1/cc) in the altitude range from 74km to 85km. The estimated errors of the electron density vary in the range from -20% to +30% even if the collision frequency has the fluctuation of ±30%. This method gives a fine structure of the electron density in the D region compared with the VLF absorption method., 資料番号: SA0166891000},
