Post-Volcanic Aerosol Altitude and Particle Size Measurements Basing on Twilight Sky Polarimetry
Oleg S. Ugolnikov, Igor A. Maslov
Measurements of the background intensity and polarization of the twilight sky were conducted during the "purple lights" epoch that was potentially caused by the Raikoke volcano eru…
Polarization Analysis and Probable Origin of Bright Noctilucent Clouds with Large Particles in June 2018
Oleg S. Ugolnikov, Igor A. Maslov
A sequence of very bright noctilucent clouds (NLC) was observed in central Russia during the last decade of June, 2018. It followed the meteorite impact 300 km southwards from Mosc…
Optical Depth and Vertical Profile of Stratospheric Aerosol based on Multi-Year Polarization Measurements of the Twilight Sky
Oleg S. Ugolnikov, Igor A. Maslov
The method of detection of light scattering on stratospheric aerosol particles on the twilight sky background is considered. It is based on the data on sky intensity and polarizati…
Detection of Molecular Scattering Field by Polarization Analysis of Sky Background During the Transitive Twilight and Temperature Measurements near the Stratopause
Oleg S. Ugolnikov, Igor A. Maslov, Boris V. Kozelov
The simplest version of the method of detection of single molecular scattering basing on the polarization measurements of the twilight sky background by all-sky cameras is consider…
Stratospheric Aerosol Particles Size Distribution Based on Multi-Color Polarization Measurements of the Twilight Sky
Oleg S. Ugolnikov, Igor A. Maslov
Polarization measurements of the twilight background with Wide-Angle Polarization Camera (WAPC) are used to detect the depolarization effect caused by stratospheric aerosol near th…
Background Stratospheric Aerosol Investigations Using Multi-Color Wide-Field Measurements of the Twilight Sky
Oleg S. Ugolnikov, Igor A. Maslov
First results of multi-wavelength measurements of the twilight sky background using all-sky camera with RGB-color CCD conducted in spring and summer of 2016 in central Russia (55.2…
