Paper Abstract

A rotational Raman lidar system at a wavelength of 355 nm has been developed for measuring the vertical temperature profile of the planetary boundary layer in the lower troposphere. A high-resolution grating is employed with two sets of narrowband interference filters to suppress the elastic Mie- and Rayleigh-scattering signals and to separate two rotational Raman signals for temperature retrieval. The central wavelength of two interference filters are located at 353.9 nm and 352.5 nm, respectively, in which wavelength temperature coefficients of rotational Raman spectral are opposite in sign. The preliminary experiments are carried out for verifying the feasibility of the prototype of the ultraviolet RRL, and the results show that the temperature sensitivity of the system is 0.43%/K and the statistical temperature errors of less then 1K are obtained up to a height of 2 km for nighttime with 300 mJ laser energy and observation time of ~8 min.
