Abstract:

The paper presents the results of observations of wildfire aerosol (WFA) layers in the stratosphere at altitudes from 11 to 16 km with aerosol and fluorescence lidars. In eight WFA measurements conducted in 2023 and 2024, both backscatter depolarization 10–25% and fluorescence of WFA were simultaneously observed. Maximal fluorescence of with excitation at a wavelength of 355 nm was observed in the 560 ± 20 nm channel and varied within the range 1–60 tm^-¹ sr^-¹ nm^-¹. The results show that fluorescence receiving channels provide important additional information for studying WFA properties in the stratosphere.
