摘要：
We propose a new method to calibrate the effect of overlap for temperature measurements made with a pure rotational Raman lidar. This method is based on the construction of a factor in the signal intensity ratio, which has an approximately linear relationship with altitude within the troposphere and can be obtained from radiosonde temperature measurements. Using this relationship, the effect of overlap on the signal intensity ratio can be calibrated. The method has been verified by simulations and an experiment. Comparisons with results obtained from using the existing calibration method show that the overlap determined using the new method is more accurate.
