[Abstract]

　The importance of the stratospheric nitrogen chemistry is recognized related to the heterogeneous reactions in both polar and mid-latituderegions. Daily measurements of slant column amounts of N0₂ and 0₃ continues successfully at Kiso Observatory(36゜N, 138゜E) of the University of Tokyo from November 1992. Slant column amounts of N0₂ and 0₃ measurements at Rikubetsu(43゜N, 144゜E) started April 1994. The data obtained at Rikubetsu and Moshiri Observatory(44゜N, 142゜E) show good agreement. A stellar occultationspectrometer has been developed and tested its performance using stars in Tokyo.
