Relative humidity drift #220
Description
After cold periods, the hygrometers can sometime get uncalibrated, leading to large differences between the upper and lower measurements. When possible the RH value w.r.t. ice is inspected to determine which level got uncalibrated. These decalibrated measurements are currently removed when spotted, in the future, a ad hoc recalibration procedure (such as https://doi.org/10.5194/essd-13-4331-2021) should help to harmonize all humidity measurements.
