Cover Story: Accurate retrieval of atmospheric water vapour from Raman lidar measurements requires the evaluation of the differential atmospheric transmission term, which accounts for extinction differences between molecular reference (nitrogen and oxygen) and water vapour wavelengths. This study investigates its sensitivity for two optical configurations: vibrational–rotational Raman nitrogen (387 nm) and pure-rotational Raman molecular near 354 nm, both with the vibrational–rotational water vapour channel at 408 nm. The results indicate that neglecting this term may cause up to 18% systematic biases. An operational method based on aerosol optical depth and an exponential decay of aerosol concentration is proposed to estimate this term automatically, transforming systematic uncertainties into random ones and improving water vapour retrieval accuracy. View this paper
