| 摘 要： | Lidar （Light detection and ranging） system monitoring of the atmosphere is a novel and powerful technique tool. The Raman lidar is well established today as a leading research tool in the study of numerous important areas in the atmospheric sciences. In this paper, the principle of Raman lidar technique measurement CO2 concentration profile is presented and the errors caused by molecular and aerosol extinction for CO2 concentration profile measurement with Raman lidar are also presented. The standard atmosphere extinction profile and ＇real-time＇ Hefei area extinction profile are used to conduct correction and the corresponding results are yielded. Simulation results with standard atmosphere mode correction indicate that the errors caused by molecule and aerosol extinction should be counted for the reason that they could reach about 8 ppm and 5 ppm respectively. The relative error caused by Hefei area extinction correction could reach about 6%. The errors caused by the two components extinction influence could produce significant changes for CO2 concentration profile and need to be counted in data processing which could improve the measurement accuracies.

| Abstract: | Lidar (Light detection and ranging) system monitoring of the
atmosphere is a novel and powerful technique tool. The Raman lidar is
well established today as a leading research tool in the study of
numerous important areas
in the atmospheric sciences. In this paper, the principle of
Raman lidar technique measurement CO2 concentration profile is
presented and the errors caused by molecular and aerosol extinction
for CO2 concentration profile measurement with Raman lidar are
also presented. The standard atmosphere extinction profile and
`real-time' Hefei area extinction profile are used to conduct
correction and the corresponding results are yielded. Simulation
results with standard atmosphere mode correction indicate that the
errors caused by molecule and aerosol extinction should be counted
for the reason that they could reach about 8 ppm and 5~ppm
respectively. The relative error caused by Hefei area extinction
correction could reach about 6%. The errors caused by the two
components extinction influence could produce significant changes for
CO2 concentration profile and need to be counted in data
processing which could improve the measurement accuracies. |
