Outline of Final Research Achievements

We conducted observational studies of the upper mesosphere and lower thermosphere which is the transient region between the earth atmosphere and the space with the multi-beam lidar, EISCAT radars, a photometer, a millimeter-wave spectrometer, and a digital camera operated at Tromsoe (69.6 deg N, 19.2 deg E). A new receiver system utilizing a 60 cm telescope was developed and installed into the multi-beam lidar: this addition enabled us to observe temperature, wind velocity, and sodium density with 3 times higher signals along the vertical direction. We obtained new findings based on (1) a detailed investigation of the formation of an additional sodium density peak at altitudes of 79-85 km below the main peak of the sodium layer by using sodium lidar and all-sky imager (OH) data, (2) an investigation of 630 nm emission timing by using photometer and spectrograph data, and (3) an investigation of change of the turbopause altitude over 25 years from 1996 to 2021 by using MF radar data.

Academic Significance and Societal Importance of the Research Achievements

地球大気と宇宙を繋ぐ遷移領域である、北極域中間圏・下部熱圏(高度70-120 km)における大気変動、大気波動の影響、微量原子密度変動、乱流圏界面高度の長期変動に関する新たな知見を得た。5波長フォトメータによる沿磁力線方向観測を実現し、オーロラ発光(波長630 nm)問題に関する知見を増した。これらは、人類の宇宙進出や、太陽風エネルギー流入による地球環境変動の理解につながる研究成果である。
