Abstract. The potential accuracies (efficiencies) of lidar techniques for measuring the atmospheric (tropospheric) temperature are compared. These techniques are based on the temperature dependence of: the envelope of the rotational Raman scattering (RRS) spectrum, the shape of the RRS spectral lines, the shape of the Rayleigh-Brillouin scattering (RBS) spectral line. The effect of the background is also taken into account. It is shown that the techniques based on Rayleigh (or Rayleigh-Brillouin) scattering are more efficient due to higher signal power and sensitivity, and more effective suppression of the background.
