南极长城站大气臭氧和NO_2的观测研究

Measurement of the O_3 and NO_2 column abundance at the Great Wall Station Antarctica

在中国第五次南极考察社长城站的科学研究活动中,开展了与南极臭氧洞有关的大气臭氧和NO_2柱含量的观测。观测采用地面吸收光谱的原理进行。从1988年12月到1989年2月的观测结果表明,长城站区臭氧柱含量平均值为341DU,与常年平均结果相当。NO_2的平均柱含量为2.16×10^(18)cm^(-2)。无论是臭氧或NO_2的柱含量都有明显的日变化。

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 310-400 DU with average 341 DU,while the NO2 gives a average value of 2.16 × 1010cm-2.
