On the Atmospheric Transmission of Sun Radiation and on Dust in the Air
TLDR
In this paper, the atmospheric transmission of Sun Radiation and on Dust in the Air are discussed. But they do not consider the effect of dust in the air on the transmission of sun radiation.Abstract:

Broadband Extinction Method to Determine Aerosol Optical Depth from Accumulated Direct Solar Radiation
TL;DR: In this paper, two models of &ldquo=uivalent” μ0 are developed for two cases of hourly and daily pyrheliometer data, that is, how to select a suitable cosine of the solar zenith angle (μ0) and how to eliminate or minimize cloud effects.

TL;DR: In this paper, the wavelength-dependent optical absorption coefficients (OACs) of atmospheric aerosols were measured at a sub-urban site in Budapest under wintry conditions simultaneously with a commercially available, seven-wavelength (7 λ ) Aethalometer instrument, and with a recently developed four-wvelength (1064, 532, 355 and 266 nm) photoacoustic spectrometer (4 λ -PAS).

A new approach for retrieving the UV–vis optical properties of ambientaerosols
TL;DR: In this article, the optical coefficients and the single-scattering albedo of the total aerosol population over 300 to 650 nm wavelength were retrieved using extinction measurements from a broadband cavity-enhanced spectrometer at 315 to 345 nm and 390 to 420 nm, respectively.

TL;DR: In this article, the authors presented the first spatially resolved detailed characterization of PM2.5 in two major Estonian cities, Tallinn and Tartu, using a high-resolution time-of-flight aerosol mass spectrometer.
