abstract = {This study assesses the effect of the differential atmospheric transmission term in Raman
lidar water vapour mixing ratio retrievals. Such issue is evaluated for two optical configurations: the first is a vibrational–rotational Raman nitrogen (∼387 nm) and the second
is a pure–rotational Raman molecular reference near 354 nm (nitrogen and oxygen). Both
optical configurations use a vibrational–rotational water vapour channel at ∼408 nm. More
than 300 aerosol profiles acquired by the University of Granada Raman lidar over the period
2010–2016 enabled the calculation of the aerosol contribution of the differential atmospheric
transmission term, indicating that neglecting the total differential atmospheric transmission
term can introduce systematic uncertainties in water vapour mixing ratio retrievals of
approximately 5.1% and 15% (18% under high-aerosol conditions) at 6 km for the first and
second configuration, respectively. Subsequently, in order to apply automatic differential
transmission calculations, we developed a technique for estimating the aerosol contribution
from sun photometer AOD measurements, yielding relative deviations in water vapour
mixing ratio of 0.10% and 0.40% for ∼387 nm and ∼354 nm configurations when compared
with cases where Raman lidar aerosol profiles were available. This approach transforms
systematic uncertainties into random ones that can be reduced by increasing the number
of measurements.},
