Abstract

We study the spatial spectra of aerosol density fluctuation from the spectra of the fluctuations of the scattered signals acquired in experimental flights of the all-European scientific project DELICAT (DEmonstration of LIdar based Clear Air Turbulence detection). We selected flight segments with constant altitude, direction and speed of the aircraft. The signal is represented as a function of two coordinates: the distance from the aircraft to the scattering volume – the path of the aircraft relative to the air mass, obtained by integrating the airspeed. Then aerosol clouds are visualized as bands inclined at an angle of 45 degrees. We evaluate two-dimensional spatial spectra of aerosol density fluctuations. In these spectra pronounced ridges along the diagonal are observed. The diagonal cross-section of the spectra corresponds to one-dimensional spatial spectra along the line of sight. A possible relation between the atmospheric density spectra and the aerosol density spectra will be the subject of the further study.
