Abstract Aerosol measurements were conducted from the Alfred Wegner Institute POLAR 6 DC-3 aircraft on 11 flights during March 22, 2012 to April 6, 2012 between Longyearbyen, Svalbard, Norway and Eureka, Nunavut, Canada. The measurements included particle size distribution (DMT UHSAS), refractory black carbon (rBC) number and mass (DMT SP2), particle light scattering (TSI 3563 Nephelometer) and particle absorption (NOAA CLAP). Our analysis uses the profile data from the flights to study new particle formation (NPF) and factors controlling the aerosol single scatter albedo (SSA). Evidence for NPF formation is found in clean air coming off Greenland in the 2-3 km altitude range. The SSA is examined with respect to the measurements of rBC, particle size distributions and light scattering.
