Two-Component Optical Model of Stratospheric Aerosol and Its Application to Interpretation of Lidar Measurements
Biomass burning aerosol has a significant effect on radiation properties of the stratosphere. Some known data about this aerosol type pertain to the cases of dense and altitudinally localized aerosol layers. Optical properties of its background component remain unknown. The processing of two-wavelength (355 and 532 nm) lidar measurements in Obninsk over 2012–2023 was performed to determine them. Lidar data interpretation is based on a two-component model of stratospheric aerosol proposed in this work. Along with the main component (sulfuric acid aerosol), biomass burning aerosol (brown carbon) is considered. As a result, the optical thickness of brown carbon aerosol in the 10–30 km layer is estimated at ∼0.012 and 0.0013 for attenuation at 355 and 532 nm and ∼7.1 × 10−3 and 3.5 × 10−4 for absorption at the same wavelengths. The results can be used in the development of advanced radiation models of the stratosphere.
期刊介绍：
Atmospheric and Oceanic Optics is an international peer reviewed journal that presents experimental and theoretical articles relevant to a wide range of problems of atmospheric and oceanic optics, ecology, and climate. The journal coverage includes: scattering and transfer of optical waves, spectroscopy of atmospheric gases, turbulent and nonlinear optical phenomena, adaptive optics, remote (ground-based, airborne, and spaceborne) sensing of the atmosphere and the surface, methods for solving of inverse problems, new equipment for optical investigations, development of computer programs and databases for optical studies. Thematic issues are devoted to the studies of atmospheric ozone, adaptive, nonlinear, and coherent optics, regional climate and environmental monitoring, and other subjects.
