摘要
The content of NO_2 in the atmosphere is one of the important factors for atmospheric environmental appreciation. An automatic solar spectrophotometer (ASS) system has been developed in order to observe the content of NO_2 in the atmosphere. The column content of atmospheric NO_2 has been obtained by use of radiative transfer equation and maximum resembled method, through the ground-based observation of direct solar radiative spectrum of 4470—4490. Some months' observations of NO_2 have been made in the suburbs of Beijing. The results have been discussed here.
