Paper Abstract

The effect of meteorological parameters on the spectral aerosol extinction coefficients ε(λ) in the near-surface layer of the marine and coastal atmosphere is studied. The results obtained are of interest both in the calculations of radiative characteristics of the atmosphere, and in the calculations of energy properties of the optical signals in optical-electronic devices of different purposes in the wavelength range ▵λ = (0.2 – 16) μm.
The MaexPro model is shown to calculate adequately ε(λ) and concentration of sea salt aerosol (SSA) particles for different wind regimes, fetches, and humidity. The calculated ε(λ) profiles well agree with experimental data and with calculations using ANAM code. The results thus obtained give a new explanation for the effect of decreasing transparency, manifested in coastal zone, and make it possible to account for indirectly the type (marine or coastal) of air mass.
