用太阳光谱法测量得到了中国新疆(38.4°-48.7°N,75.0°-89.5°E)地区以及其它一些大城市如北京(39.99°N,116.30°E)、成都(30.63°N,104.09°E)、厦门(24.44°N,118.10°E)和香港(22.34°N,114.17°E)的NO2柱体密度.新疆NO2的垂直柱体密度介于7.5×1015(卡拉库勒湖,38.44°N,75.05°E)和1.41×1017 molecules/cm2(乌鲁木齐,43.81°E,87.60°E)之间.北京、成都、香港和厦门的NO2垂直柱体密度分别为8.50×1016、7.42×1016、5.62×1016和4.92×1016 molecules/cm2.将新疆NO2污染程度与中国其它几个主要城市进行对比,可为反映中国西部地区工业快速发展提供参照.%Solar spectroscopic measurements were performed to obtain the nitrogen dioxide (NO2) column density in Xinjiang (38.4°-48.7°N, 75.0°-89.5°E) and in other major cities of China, including Beijing (39.99°N, 116.30°E), Chengdu (30.63°N, 104.09°E), Xiamen (24.44°N, 118.10°E), and Hong Kong (22.34°N, 114.17°E). In Xinjiang, the NO2 vertical column densities (VCD) range from 7.5×1015 (Lake Karakul, 38.44°N, 75.05°E) to 1.41×1017 molecules/cm2 (Urumqi, 43.81°N, 87.60°E). In Beijing, Chengdu, Hong Kong, and Xiamen, the VCD amounts are measured to be 8.50, 7.42, 5.62, and 4.92×1016 molecules/cm2, respectively. In response to the rapid industrial development in the western regions of China, the measurement results provide a reference NO2 pollutant level in Xinjiang in comparison to that of in other major cities of China.
