Biomass Burning Aerosol Fluorescence Spectra

JRJens ReichardtFLFelix LauermannOBOliver Behrendt

Key Points

  • To characterize the fluorescence spectrum of biomass burning aerosol using lidar measurements.
  • Measurements conducted with the RAMSES spectrometric fluorescence and Raman lidar in June 2023
  • Analysis of fluorescence spectra across different heights
  • Assessment of correlations between fluorescence and optical properties.
  • BBA spectra are generally Gaussian with peak wavelengths around 500-550 nm
  • Spectra shift to longer wavelengths with increasing height
  • Weak correlation between fluorescence and elastic optical properties.

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.
