Comparison of Aerosol Optical and Microphysical Characteristics at Different Regions

Golitsyn, G.S., Anikine, P.P., Isakov, A.A., and Sviridenkov, M.A., Oboukhov Institute of Atmospheric Physics, Russian Academy of Sciences
Ninth Atmospheric Radiation Measurement (ARM) Science Team Meeting

During the last decade, spectral solar aureole measurements were carried out at different regions by the Institute of Atmospheric Physics, Russian Academy of Sciences; Tadjikistan, Oklahoma, Spitsbergen, the Moscow Region and near the Aral Sea. The measured characteristics were inverted to the aerosol size distributions in the atmospheric column. The size spectra obtained can be roughly approximated by the power law and more precisely as a sum of several lognormal modes. Parameters of the approximating distributions are given. The similarities and distinctions in size distributions at different places are discussed. The possibility of the retrieval of the aerosol parameters, (e.g., volume concentration from measurement data without a solution for the inverse problem) is analyzed.
