摘要
利用地面可见光 (4 30— 45 0nm)波段的太阳光谱和大气上界的参考太阳光谱 ,反演出大气中NO2 的柱总含量 ,得到了该地区上空NO2 含量及其变化 ,其变化与当地环境监测站用常规法测量的NO2 浓度的变化基本一致。该文介绍了测量仪器。
The vertical column abundance of atmospheric NO 2 was measured with ground based solar spectra and a reference extraterrestrial spectrum in the visible wavelength range of 430—450 nm. The vertical column abundance and its variations of NO 2 in the region of Hefei were obtained from the measuremental data from the November to the end of December of 1999. The variation trends basically coincided with the surface density of NO 2 measured independently with conventional instruments on the ground. The instruments, principles of measurement and some of results were introduced.
