Abstract:In the Fifth Antarctic Research Expedition of China(1988-1.989),the high resolution spectra of the ,sun were obtained at Great Wall Station "from Dec.1988 to Feb.1989.The waveband used to reduce the O3 ane NO2 column abundance are 300-340 nm and 444-450 nm,respectively.The results of this measurement are discussed.The O3 .column abundance in this measurement varies in the range of 316-400 DU with average 341 DU,while the NO2 gives a average value of 2.16 × 1616cm-2.
