Cloud radars provide information on micro- and macrophysical properties of clouds and precipitation. Continuous zenith-pointing cloud radar observations were made with the 94 GHz (W-band) frequency modulated continuous wave Doppler radar (model RPG-FMCW-94-SP) named JOYRAD-94. Measurements were carried out at the AWIPEV Atmospheric Observatory in Ny-Ålesund, Svalbard, from 14 June 2019 to 22 June 2022. The atmospheric column from 100 m to 12 km above the surface was profiled with a vertical resolution of 3.2-24 m and a temporal resolution of 2 s. The data was post-processed to correct for Doppler aliasing and the radar calibration was adjusted based on a reference radar. The data includes the equivalent radar reflectivity factor, mean Doppler velocity, and skewness and kurtosis of the Doppler spectra. Some technical parameters and flags related to measurement operation, post-processing, and data quality, which could be relevant for some data users, are also provided.
