We present results obtained during the ''AGASP 1983'' Arctic haze aircraft sampling experiment. We collected many filter samples and operated the LBL aethalometer, an instrument that responds to the aerosol graphitic (''black'') carbon concentration in real time. We found substantial concentrations of black carbon and sulfur at all altitudes in the Arctic troposphere. Maxima in the black carbon concentrations were observed at intermediate altitudes. Comparing these results with data from the NOAA-GMCC observatory near Barrow, Alaska, we find that peak concentrations aloft can be significantly greater than the ground-level measurements.
