Using the Raman channels of the Koldeway Aerosol Raman Lidar (KARL) a water vapour mixing ratio is derived.Data is availiable for all measurements during the dark season since 2015.Calibration in the winters 2015/2016 and 2016/2017 was performed using the GRUAN radiosounding product.For comparison those winters where recalculated with radiosounding measurements processed by the Vaisala Algorithm.The winter 2017/2018 is calibrated using radiosounding measurement from the RS41processed by the Vaisala Algrithm.The details of the calibration of this water vapour product are explained in Kulla & Ritter 2019.

Spatial resolution: 60mTemporal resolution: 10MinutesDifferent temporal and spatial resoltions can be prepared if needed.Calibration performed 2018-11-22.
