From net-flux radiometer measurements an model results, we deduce the vertical layer structure of the Arctic haze encountered during two of the AGASP flights. We find the total value of the absorption optical depth to be on the order of 0.065 for both flights, with the majority of the absorbing aerosol concentrated in the lowest 1.6 km of the atmosphere. A comparison of these results with measurements of the carbon concentration (Rosen et al., 1984) leads to a value of the specific absorption of carbon of 24 m2/g. While higher than expected, this value is shown to be consistent with an internally-mixed aerosol of carbon cores and sulfate shells.
