Abstract:

Linear estimation method is used to determine the integral parameters of atmospheric aerosol, such as volume density and effective radius from the spectra of aerosol optical depth measured by a sun photometer. For approbation of the method, three-month series of optical depth at seven wavelengths for four cites of AERONET network characterized by different aerosol types: urban, biomass burning, desert dust, and marine, were chosen. Comparison of the results with retrievals from standard AERONET algorithm shows a good agreement between two methods. However, linear estimation technique allows retrieving time series of particle parameters from direct sun measurements with a high temporal resolution of about several minutes. This method can be used in the instruments that do not provide angular scanning of sky radiance, e.g., the PFR/GAW sun photometers network.

Keywords:

atmospheric aerosol (aerosols in atmosphere), retrieve of atmospheric aerosol parameters, linear estimation method
