摘　　要：为了促进大气成分业务观测水平的提高,对阿克达拉区域大气本底站新建设的NO_x、SO_2、CO和O_3 4种反应性气体集成观测系统的构造、功能以及质量控制方法进行了介绍,分析了在站址科学论证期间观测到的O_3和CO的浓度水平和变化特征,并与其他本底站的观测结果进行了比较,给出了新观测系统的一些初步观测结果。结果表明,阿克达拉站观测到的O_3和CO的浓度水平及其变化特征有别于中国东部几个大气本底站的观测结果,反映了该站与其他站的差异;新的观测系统自动化程度较高、易于实现质量控制,其性能指标能够满足该偏远站点观测的需求。In order to improve the operational observation of atmospheric compositions,the in-situ observation system of NO_x,SO_2,CO,and O_3 for the Akedala regional atmosphere background station is developed,and its structure,functions,and quality control methods are introduced.The observed O_3 and CO levels at Akedala during the period of scientific evaluation of the site are characterized and compared with those observed at other background stations.Some preliminary data for NO_x,SO_2,CO,and O_3 collected using the new observation system are also given.The results show that the characteristics of the observed concentrations and variations of O_3 and CO at Akdala station are different from those from the background stations in the eastern China,which reflects the differences between Akedala and other stations.The new observation system possesses a high degree of automation so that the quality control is easy to implement.Its performance indicates that the specifications of the system meet the needs of observation at the remote site.
