The ratio of lidar return at unbiased wavelength of 532 nm to a sum of lidar returns from two regions of the rotational spectrum of Raman scattering (RS) by nitrogen and oxygen molecules is used to measure the light backscattering coefficients. The ratio of the rotational RS intensities from two spectral regions can determine the vertical temperature profile; the ratio between the RS signals and temperature values from two adjacent segments of the path are used to calculate the extinction coefficients. The measurement errors and the ways to lower them are also discussed in the paper.
