Preliminary results of the ACTRIS ACSM intercomparison study at the SIRTA French Atmospheric Supersite in the region of Paris

Abstract : As part of the EU-FP7 ACTRIS program (Aerosols, Clouds, and Trace gases Research InfraStructure Network; http://www.actris.net), 14 of 19 ACSMs (Aerosol Chemical Scpeciation Monitor; Aerodyne Research Inc., MA, USA) have been deployed for long-term observations within background monitoring stations, among which the French SIRTA atmospheric supersite (Site Instrumental de Recherche par Télédétection Atmosphérique; http://sirta.ipsl.fr) located 20km southwest of Paris. In order to have homogenous quality-controlled ACSM datasets at an European scale, an intercomparison study was conducted from 15 Nov. to 2 Dec. 2013 at the SIRTA station. The real-time mass concentrations and chemical composition (Organic, nitrate, sulfate, ammonium) of nonrefractory submicronic aerosols (NR-PM1) measured by the ACSMs were compared providing new insights on the precision of this instrument. Accuracy of these measurements was then evaluated with various co-located instruments (TEOM-FDMS, SMPS, OPC, OC-EC Sunset Field analyzer, PILS-IC, HR-ToF-AMS, aethalometers, nephelometers, filter sampling). Preliminary results of this significant intercomparison stduy are presented which compare ACSM measurement precision, accuracy and validity of source apportionment data.
