Measurements of micro rain radar at AWIPEV, Ny-Ålesund (2017-2021)

The Micro Rain Radar (MRR; type MRR2) - manufactured by Meteorologische Messtechnik GmbH (Metek) - is a vertically pointing frequency modulated continuous wave (FM-CW) Doppler radar operating at 24.1 GHz (K band). The backscattered signal by falling hydrometeors is measured at 32 range gates. This data includes the output of the Improved MRR Processing Tool (IMProToo; Maahn and Kollias, 2012) for the MRR measurements at AWIPEV in 2017-2021. IMProToo provides reliable values of equivalent radar reflectivity Ze, Doppler velocity and spectral width among other variables.
