Abstract
Airborne measurements made during August 1985 over Greenland and its environs show that both accumulation-mode (0.1 μm ≤D≤2.0 μm) and giant (D≥2 μm) particles were present in relatively high concentrations in arctic haze layers and that the accumulation-mode particles dominated light scattering. Particles with diameters (D) between ∼ 1 and 4 μm consisted predominately of mixed materials, small and dense inclusions, and probably organic compounds containing sulfur. Many of the particles from 0.1 to 1 μm in diameter were also of mixed composition, with sulfuric acid, ammonium sulfate and organics probably the dominant constituents.
