A.; Sheridan, P.; Virkkula, A.; Weingartner, E.; Weller, R.; Laj, P. (Copernicus GmbH, 2013-01-22)
      Currently many ground-based atmospheric stations include in-situ measurements of aerosol physical and optical properties, resulting in more than 20 long-term (> 10 yr) aerosol measurement sites in the Northern ...
