Short summary
In recent updates of the HITRAN water vapour H2O spectroscopic compilation covering the blue spectral region (here 394–-480 nm) significant changes for the absorption bands at 416 and 426 nm were reported. In order to investigate the consistency of the different cross sections calculated from these compilations, H2O vapour column density ratios for different spectral intervals were retrieved from long-path and multi-axis differential optical absorption spectroscopy measurements.
