Construction and analysis of long-term series of aerosol microstructure parameters reconstructed from the data of solar photometry in Tomsk

摘要

Results of investigations of the time variability of microstructure aerosol parameters reconstructed by inversion of spectral measurements of the aerosol optical thickness (AOT) are presented. The input data were obtained at the IAO SB RAS using solar photometers of SP type in the observation periods 2003-2006 and 2011-2014. During the first period of measurement, the AOT was measured at 13 wavelengths in the range 0.37-4 μm. During the second observation period, the upper limit of the spectral range of measurements was 2.14 μm. The total volume of the data processed included over 6 thousands hour-averaged spectra. The geometric aerosol cross section, volume concentration, and average particle radius are analyzed.
