Water vapour mixing ratio over Ny-Alesund from LiDAR measurements 2015-2018
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.
