Results from preparatory stage of studying the seasonal and interannual variations in atmospheric aerosol optical depth (AOD) at two Arctic stations on the Spitsbergen Archipelago (Ny-Ålesund and Barentsburg) are presented. The first task in the preparatory stage was to identify and sort out suspect measurements of spectral AOD in multiyear time series of observations at the Ny-Ålesund station. The second task was to select an optimal method of estimating two AOD components, caused by attenuation of radiation by fine- and coarse-mode aerosol. Comparative analysis of application of four types of methods showed comparable results: average error of estimating two AOD components is less than 0.01.
