TU Delft Cloud radar data - LARA Slant Profiles
Wat erin zit
Description: Slant profiles of clouds and precipitation measured by 94 GHz cloud radar: W-band polarimetry and spectral polarimetry of precipitation, ice, and mixed-phase clouds. This dataset contains slant profiles of clouds and precipitation observed using a dual-polarization frequency-modulated continuous-wave (FMCW) cloud radar located at the atmospheric site Lutjewad. The radar, developed by Radiometer Physics GmbH (RPG-FMCW94-DP type) and named Lutjewad Atmospheric RAdar (LARA), operates at 94 GHz. LARA is situated on a 10-meter-high platform. It employs simultaneous transmission and simultaneous reception (STSR) mode and its beamwidth is 0.56°. There is a rain/snow/fog mitigation system, comprising a dew blower and a heater which prevent the accumulation of liquid drops and ice on the hydrophobic antenna radomes, therefore mitigating attenuation caused by the presence of liquid water on the antennas. Measurements are collected at a fixed elevation angle and constant azimuth. The default elevation angle is 45°. However, measurements at 30° elevation angle are also carried out. LARA includes an embedded passive channel at 89 GHz, enabling Liquid Water Path (LWP) retrieval …
