Méthodologie d'acquisition et qualitéParticle Size Spectrum provided in 90 nominal size classes over time scans lasting 90 s. Given 30 s of down time, time resolution is 120 s. SMPS size distribution corrected for multiple charge and diffusion loss. In cloud data removed. SMPS scans with altitude variation of more than 100m removed. SMPS scans with inhomogeneous aerosol population evaluated as min(CPC) < 0.3*max(CPC) removed. SMPS integrated aerosol concentration compared to condensation particle counter with no nucleation particle present.

Méthodologie d'acquisition et qualitéLog normal fit parameters based from equation N_i/(sqrt(2*pi)*log(sigma_i))*exp(-(log(D)-log(D_i))^2/(2*log(sigma_i)^2). Where N_i is the mode number concentration, sigma_i is the geometric standard deviation and D_i is the mean geometric diameter. Size ranges for nucleation(i=1), Aitken(i=2) and accumulation(i=3) mode fits were between particle sizes of 10 to 50nm, 50 to 100nm and 100 to 400nm, respectively.
