Abstract

Measurements with the spectrometric fluorescence and Raman lidar RAMSES in June 2023 are used to illustrate the general characteristics of the fluorescence spectrum of biomass burning aerosol (BBA). The BBA spectrum is often layer-specific, quite Gaussian with a center wavelength in the range of about 500 to 550 nm, and tends to shift to longer wavelengths with height. Fluorescence and elastic optical properties of BBA are only weakly correlated.
