| 摘 要： | 利用机载DMT云凝结核计数器观测了2009年10月13日陕西关中西部晴空云凝结核（CCN）的垂直分布。分析结果显示：关中西部晴天地面CCN平均浓度在过饱和度为0.2%时大于10000个/cm3,大雾天气下地面CCN浓度明显高于晴天。CCN浓度随高度增加而递减,1500 m以下为高值区,1000 m、1550 m、4100 m、5500 m高度的CCN平均浓度在过饱和度为0.4%时分别为8827个/cm3、4439个/cm3、456个/cm3、504个/cm3。

| Abstract: | Vertical distributions of cloud condensation nuclei（CCN） in a cloudless sky were observed by the DMT（Droplet Measurement Technologies） CCN counter mounted on an AN-26 airplane in the western Guanzhong area of Shaanxi Province on 13 October 2009.The results of observation show that the ground average concentration of CCN was more than 10000 cm-3（supersaturation was 0.2%） under a cloudless sky condition,and the ground CCN concentration for foggy days on 7 October 2009 was significantly higher.The CCN concentration tends to decrease with height.CCN concentration was high below 1500 m,with the mean CCN concentration being 8827 /cm3,4439 /cm3,456 /cm3,504/ cm3（supersaturation equals 0.4%） at the levels of 1000 m,1550 m,4100 m,5500 m,respectively. |
