INVESTIGATION OF CONTINUOUS MEASUREMENT OF SO2, NO2 CONCENTRATION IN FLUE GASES BY DOAS WITH KALMAN FILTER
In the past decades, Differential Optical Absorption Spectroscopy(DOAS) has been widely used for monitoring of trace gases1-5 in the stratosphere or troposphere. It was platt et al.1-2 who first started to utilize the differential absorption for tropospheric gas composition measurement simultaneously without disturbing the chemical behaviors of substances to be investigated. The most straightforward atmospheric molecules to detect with DOAS are SO2, NO2 and O35-7 in the u.v./visible. In the tropospheric application, the light from a broad band xenon lamp is transmitted through the atmosphere for distances up to several kilometers.
