摘要: The several advantages of Raman lidar for remote measurements stationary source emissions were quantitatively evaluated using a calibration tank at distance 300 m night. Measurements ~103-ppm SO2 with 12% accuracy demonstrated in an observation time 15 min 1.5-J ruby laser 30 pulses/min, 6-m range resolution, interference filters, photon counting detection, and 20-cm receiver. Measurement was checked by measuring known concentrations the tank, tuning filters through line, varying CO2 concentration to very high levels during measurements. Evaluation seriousness induced fluorescence from plume aerosols failed due inability simulate aerosols.
