A coherent Doppler lidar (CDL) operating at 532.25 nm wavelength with a 3.2 GHz data acquisition is developed. The technical setup is described. One atmospheric measurement case is analysed to point out the instrument's ability to observe cloud, precipitation, and aerosol particles of very different sizes in one Doppler spectrum. A second case highlights the coherent detection of the broadband Rayleigh-Brillouin (RB) spectrum and the possibility for a Mie signal calibration. The system's benefits compared to 1.55 µm CDLs are discussed. The system's capabilities were found to be promising for enhancing the knowledge about aerosol-cloud interactions.
