For 10 days in August, 1986, equipment from many different organizations was set up at a location in the suburban Los Angeles area for sampling carbonaceous pollutant species in all forms. The authors report here on the intercomparison of two quite dissimilar sampling and analysis methods for aerosol elemental carbon. The two methods being compared are: University of Minnesota - impactor samplers with one or more stages, backed up by a quartz fiber afterfilter; elemental carbon (EC) analysis by oxidation in helium over an MnO{sub 2} catalyst; Lawrence Berkeley Laboratory - real-time measurements with aethalometer, an optical absorption technique on a continuously collecting quartz fiber filter. The good agreement between the results suggest that there may be an approach towards an acceptable measurement standard for this important atmospheric pollutant species.
