Short summary
The aerosol climatology over 2001–2014 was obtained in Moscow within AERONET. The best data quality has been accessed after additional cloud correction, which decreases AOT up to 0.03 at 500 nm. The additional NO2 correction of up to 0.015 should be applied in megacities with large NOx emission rates. The pronounced negative AOT trends of about −1–5% per year were observed for most months, which could be attributed to the negative trends in emissions of different aerosol precursors.
