摘要
利用TERRA卫星上搭载的对流层污染测量仪(MOPITT)在2002年1～12月的探测数据,分析了2002年全球大气CO的时空分布特征,并着重对东亚地区上空的CO柱总量月平均分布及其年变化做了研究,验证和得出了一些关于CO时空分布的重要结论:CO柱总量在北半球分布高于南半球,在1月份高于7月份,南半球春季低纬有几个高值中心;东亚地区CO柱总量高值区分布在中国东部沿海以及东南亚、日本列岛之间,位置和强度都逐月变化,这一点与气象场的季节变化有关;对多个站点的讨论表明,CO浓度在一年中随季节变化。
The spatial\|temporal distribution of the global carbon monoxide concentration in 2002 is analyzed by using MOPITT (the Measurement of Pollution in the Troposphere) data sets. The results show that CO is considerably abundant in the Northern Hemisphere and reaches its maximum in January, and that there are three centers of high CO concentration between 0 and 20°S in the Southern Hemisphere during the Southern spring. It is found that the regions with high CO concentration over East Asia are those from Indonesia, through the eastern coast of China, to Japan. An obvious seasonal variation of CO column concentration is also found in different locations.
