Instrumentation: Ambient Ion Monitoring Ion Chromatographs (AIM-IC, URG Corp; Markovic et al, 2012 in J. Environ Measur.)
Measurement height: 5 m (above ground)

Inlet: impactor to remove particles larger than PM2.5, wet parallel plate denuder to capture water soluble gases, 
condensation chamber to dissolve water soluble components of PM2.5

Backgrounds: ultra pure zero air gas was introduced to the front end of the AIM inlet.
Calibrations: Ion chromatographs were calibrated off-line using liquid standards.
Flow rate: average 2.5 - 3 L/min
Time steps: 60 min
Time stamp: local standard time (MST)
