Abstract:
|
The PCASP measures an aerosol size distributions from 0.136 to 3 micrometers. Aerosols pass through a laser beam and the resulting intensity of scattered light is directly correlated to the diameter of the aerosol passing through the beam. Data flag of 1 indicates an instrument error occurred. If the PCASP number concentration exceeded the CPC3010 number concentration by greater than 25% a flag was triggered. Instrument was not maintaining volumetric flow. A correction(Conc=Conc_orig*[(1013.25/Pamb)*(Tamb/293.15)]) was applied.
