Aerosol thermooptical characteristics in different types of aerosol weather (original) (raw)

2020

Abstract

The data obtained in 2000–2017 by the method of active spectral nephelometry using artificial heating of an aerosol collected from the atmosphere up to 250°C are analyzed. The variability of thermo-optical parameters that determine the fraction of the volume concentration of particles evaporating in the corresponding temperature range depending on the type of “aerosol weather” is analyzed. Four data arrays characterized by different aerosol state were selected for each season: “background”, “haze”, “smog”, and “smoke haze”. The arrays differ in the level of concentrations of aerosol and soot. The peculiarities of the aerosol thermo-optical parameters in each type of turbidity are considered.
