At the new long-term Tall Tower monitoring facility near Zotino, Siberia (ZOTTO, 90°E, 60°N)a unique fine particle monitoring system has been set up. Through two inlets at the tower in 50 m and 300 m height aerosol particle number size distributions are measured since September 2006 in the size range of 15 to 835 nanometer dry diameter. They are representative for the aerosol over a large part of Eurasia. Up to fall 2008 the results cover a wide range of concentrations reaching from very low Arctic to suburban polluted levels. In summer there are indications of new particle formation in conditions with low pre-existing particulate surface.
