Ambient aerosol particles vary in size from a few nanometers to
several micrometers. No instrument is currently available to cover
such a wide size range, and so a combination of several instruments
is usually used. One such combination is that of electrical mobility
classifiers and an aerodynamic sizer. Because of the differences in
measurement principles between the instruments, difficulties arise
in the combination of the measurements into a single size distribution.
Here we report a simple algorithm that was developed to
combine aerosol size distributions measured with commercially
available scanning mobility particle sizers (SMPS; TSI Inc.) and
an aerodynamic particle sizer (APS; TSI Inc.). This algorithm was
tested during July 2001 in the Pittsburgh Air Quality Study. The
aerosol during the study had both urban and regional origin and |
