The aerosol optical properties in this dataset include scattering \u00c5ngstr\u00f6m exponent, light scattering coefficient, backscattering coefficient, the hemispheric backscatter ratio, and further extended by the analysis of back trajectories and satellite-derived sea ice data, to produce surface residence times and meteorological parameters.\r\n\r\nThe dataset contains hourly data based of aerosol light scattering properties including extensive parameters taken from an integrating nephelometer (TSI Inc., U.S.A., Model 3563), namely light scattering and backscattering coefficients at 550 nm. The hemispheric backscatter ratio at 550 nm and the scattering \u00c5ngstr\u00f6m exponent as calculated based on wavelengths 450 nm and 550 nm are also included.\r\n\r\nThe dataset is temporally collocated with a 7-day Hybrid Single Particle Lagrangian Integrated Trajectory model (HYSPLIT) back trajectory analysis, that includes surface residence times derived using satellite sea ice data, averaged meteorological parameters like pressure, relative humidity, temperature (medians along the back trajectories) and the average of the trajectories coordinates. The addition of HYSPLIT analysis aids in the interpretation of aerosol properties.","citations":"Heslin-Rees D, Burgos M, Hansson H-C, Krejci R, Str\u00f6m J, Tunved P, Zieger P (2020) From a polar to a marine environment: has the changing Arctic led to a shift in aerosol light scattering properties?
