| Summary: | Precipitation fallen during the summer months (November-December-January) on four expeditions, 2015-16, 2016-17, 2017-18, and 2018-19, in the Terra Nova Bay area, were monitored using a vertically pointing radar, disdrometer and snow gauge.The vertical pointing METEK Micro Rain Radar 2 (MRR) was installed in MZS at the end of November 2015. It records Doppler velocity spectra every 10 s at 32 range gates. The radar gate spacing was set to 100 m allowing the profiler to sound heights ranging from 100 to 3100 m above the surface. The raw K-band power spectra, collected by the MRR, were processed applying the method proposed by Maahn and Kollias (2012) to correct for noise and aliasing effects, making them suitable for snow observation.A Thies CLIMA laser disdrometer (LPM), has been operational since December 2014.The disdrometer can simultaneously count and measure the size and fall velocity of hydrometeors (Frasson and others, 2011).A Total Rain weighing Sensor (TRwS) manufactured by MPS system was installed ... : Dataset:Monthly zipped folder containing daily files.For files from 2015-11-01 to 2018-11-31--Five minute average profiles of Radar reflectivity (Radar_Reflectivity_MRR, dBZ), Mean Doppler Velocity (mean_doppler_velocity_MRR, m/s) and Spectral Width (spectral_width_MRR) .--One minute accumulated matrix number of particles detected by disdrometer within different fall velocities - Diameter range bins (N_particles_bin_LPM). The measurement is sampled every five minute.Velocity (Diameter) bins minimum, maximum are defined in Dia_min_bin_LPM, Dia_max_bin_LPM (Dia_min_bin_LPM, Dia_max_bin_LPM)respectively.--Quality control variable for disdrometer sensor [Quality_measurement_check_LPM, 0 (sensor failure) -100 (good measurement) ]For files from 2018-12-01 to 2019-01-31--Files contain, in addition, the five minute average of precipitated quantities (SF_TRwS, mm w.e.) evaluated as Scarchilli et al. (2020) from raw weight measurement sampled by the TRwS snow gauge. ... |
