It is shown that, under clear sky conditions, water-vapor mixing-ratio measurements by solar-blind Raman lidars can be improved if the differential transmissivity is calculated by use of a single Raman signal instead of the usual Raman differential absorption lidar method, which allows one to exploit the large absorption cross section of ozone in this spectral region. We present a discussion of statistical and systematic errors in both methods and show the results of a numerical simulation.
