Abstract

<p>In this dataset, non-refractory composition of PM2.5 measured by an Aerosol Chemical Speciation Monitor (ACSM, Aerodyne Research Inc.) is reported. The measurements are reported at 10 minute intervals. The ACSM is equipped with a PM2.5 aerodynamic lens, a standard vaporizer, and a time-of-flight mass spectrometer.</p>
