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.
