Optical-aerosol model of the Western Siberian stratosphere based on lidar monitoring results

Study of optical properties of atmospheric ice crystals of arbitrary polyhedral shape

“…The analysis revealed that, basically, the particles from the ensemble are quite close to the plot of the function of the reference particle, which clearly demonstrates the validity of the solution for the selected particle. This result demonstrates that laser sensing data of the atmosphere [23][24][25][26][27][28][29][30][31][32][33][34] can be interpreted using a reference particle database.…”

Solution of the problem of light scattering by ice non-spherical particles obtained in the approximations of geometric and physical optics for problems of laser radiation transfer

“…Since the particle sizes of cirrus clouds and large field aerosol reach 1000 µm, the generally accepted method in this case is the geometrical optics approximation [17][18][19] . However, the obtained solution is not suitable for interpreting the data of laser sounding of the atmosphere, since it cannot resolve the backscatter peak 20 , which is very important for problems of laser sounding [21][22][23][24][25][26][27][28] . This problem can be circumvented by using the method of physical optics [29][30][31] .…”

Dynamics of background stratospheric aerosol over Tomsk in 2022 from the lidar monitoring data

“…This period, similar to previous few years, was characterized by the absence of powerful volcanic eruptions, which could affect a perturbation of the aerosol component of the stratosphere of the northern hemisphere including the region of Western Siberia. Therefore, it was possible to establish special features of the vertical-temporal variability of the stratospheric filling with the background aerosol and its integral content for Western Siberia including the studies given in [1] for a sufficiently long time interval for previous years. The initial information used for analysis was the dataset of 94 total signals accumulated on single nights in 2022.…”
