Cloud radar Doppler spectra measured with MiRAC-A at AWIPEV, Ny-Ålesund (July 2017 – October 2018)


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 MiRAC-A. Measurements were carried out at the AWIPEV Atmospheric Observatory in Ny-Ålesund, Svalbard, from 28 July 2017 to 8 October 2018. 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 contains only the Doppler spectra, radar moments are available as a separate data set. 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.

The files are in NetCDF format, following where appropriate the CF convention. Each file contains the measurements for one hour.
