Water vapor profiles retrieved during the POLARSTERN cruise PS122/1, September 2019, Arctic Ocean

The dataset consists of water vapor profiles including the errors of the Raman lidar measurements performed by the PollyXT_Lidar “Arielle” in the Oceanet container at the bow area of Research Vessel Polarstern from 28 September 2019 till 29 February 2020. The profiles are averaged over 30 s and additionally smoothed with a sliding average over 10 min with the smooth2-function. The vertical averaging is 5 bins (bin-width is 7.5 m; the lidar is pointing with a Zenit angle of 5°). Additionally, signal-to-noise (SNR) ratios of the two signals (H2O and N2) and a quality mask (QM) are provided. The quality mask QM is equal to 1 if the SNR_N2<1 or the SNR_H2O
