TU Delft Cloud radar data - LARA Vertical Profiles
Wat erin zit
Description: Vertical profiles of clouds and precipitation measured by 94 GHz cloud radar. This dataset contains vertical 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 (90°). LARA includes an embedded passive channel at 89 GHz, enabling Liquid Water Path (LWP) retrieval using the same receiving antenna. Additionally, it is coupled with a HATPRO G5 microwave radiometer (LARIO), providing collocated radiometric measurements at the same temporal resolution. A built-in …
