CHARLICE - Compact Heterodyne Aerosol Rayleigh–Brillouin Lidar at 532 nm wavelength for the observation of ICE formation processes
General project description
A coherent Doppler lidar with an emission wavelength of 532 nm and broadband data acquisition (3.2 GHz) is being developed. This makes it possible to measure both aerosol and cloud particle backscattering as well as molecular backscattering. The coherent Doppler lidar is used to investigate ice formation in mixed-phase clouds. The size spectrum of the resulting ice crystals can be determined by a larger spectral separation of the particles falling at different speeds. In combination with a Doppler radar, the flow of ice particles (ice crystal number flux) and thus the formation rate of ice crystals can then be determined.
