The ToF-ACSM: a portable aerosol chemical speciation monitor with TOFMS detection
We present a new instrument for monitoring aerosol composition, the time-of-flight aerosol chemical speciation monitor (ToF-ACSM), combining precision state-ofthe-art time-of-flight mass spectrometry with stability, reliability, and easy handling, which are necessities for long-term monitoring operations on the scale of months to years. Based on Aerodyne aerosol mass spectrometer (AMS) technolo...
متن کاملLong term aerosol measurements
Introduction Conclusions References Tables Figures Back Close Abstract Introduction Conclusions References Tables Figures Back Close Abstract Long-term measurements (over 4 years) of particle number size distributions (sub-micrometer particles, 3–800 nm in diameter), trace gases (NO, NO 2 , and O 3), and meteorological parameters (global radiation, wind speed and direction, atmospheric pressure...
متن کاملSubmicron aerosol source apportionment of wintertime pollution in Paris, France by double positive matrix factorization (PMF) using an aerosol chemical speciation monitor (ACSM) and a multi-wavelength Aethalometer
Online non-refractory submicron aerosol mass spectrometer (AMS) measurements in urban areas have successfully allowed the apportionment of specific sources and/or physical and chemical properties of the organic fraction. However, in order to be fully representative of PM pollution, a comprehensive source apportionment analysis is needed by taking into account all major components of submicron a...
متن کاملTwo years of near real-time chemical composition of submicron aerosols in the region of Paris using an Aerosol Chemical Speciation Monitor (ACSm) and a multi-wavelength Aethalometer
Aerosol mass spectrometer (AMS) measurements have been successfully used towards a better understanding of non-refractory submicron (PM1) aerosol chemical properties based on short-term campaigns. The recently developed Aerosol Chemical Speciation Monitor (ACSM) has been designed to deliver quite similar artifact-free chemical information but for low cost, and to perform robust monitoring over ...
متن کاملSurface-Based Remote Sensing of the Aerosol Indirect Effect at Southern Great Plains
We have demonstrated first measurements of the aerosol indirect effect using ground-based remote sensors at the Southern Great Plains (SGP) site. The response of non-precipitating, ice-free clouds to changes in aerosol loading is quantified in terms of a relative change in cloud-drop effective radius (re) for a relative change in aerosol extinction under conditions of equivalent cloud liquid wa...
