| Abstract: | In order to testify the mensurability of high SO2 concentration and the variety of SO2 with AML-2 mobile lidar, a measurement is carried out near a power plant. The fourth harmonic of Nd:YAG laser is used to pump CH4 and D2 gas cell, and the first Stokes Raman-shifted wavelengths of 288.38 nm and 289.04 nm are obtained for SO2 concentration measurement. The maximum of SO2 concentration about 1300 ppb is got in the smoke way. 2D mappings of SO2 distribution are also presented which are detected on the windward and the leeward of the power plant . It comes to a conclusion that the exhaust gas from the power plant truly effects the environment nearby. The detecting ability of the AML-2 lidar on SO2 is also proved. |
