Short summary
Often, the emission height of the mesospheric hydroxyl layer has been inferred from a comparison of temperature measured by ground-based lidars and hydroxyl spectrometers. I use temperatures measured by two independent instruments to show that such comparisons usually lead to ambiguous height determinations, especially if a variable layer width is taken into account. Even though this dataset is from a single location, the results apply to all airglow layers at any location.
