| 英文摘要 | Development of an Autonomous Aerosol Chemical Speciation Monitor withIntegrated Calibration and Quality Assurance Capability.—AerodyneResearch, Inc., 45 Manning Road, Billerica, MA 01821-3976Philip Croteau, PrincipalInvestigator, croteau@aerodyne.comJiri Cistecky, Business Official, proposals@aerodyne.comAmount: $1,098,417 Ambient aerosol particles play a significant role inadversely affecting human health, in altering the chemistry and the radiativebalance of the Earth’s atmosphere, and in reducing visibility. However, thereare significant uncertainties in the sources and chemical transformations ofparticulate matter and how they relate to climate and health. Organic aerosolis a key component, often accounting for half or more of the total mass, and isthought to play an important role in the radiative effects of particulatematter. The characterization of sources and fates of organic aerosol in theatmosphere is crucial to our understanding of the relationship between anthropogenicactivity and global climate. Overthe past fifteen years, aerosol mass spectrometers and, more recently, aerosolchemical speciation monitors, which measure the chemical composition ofnon-refractory particulate matter, have become important tools forunderstanding the sources, sinks, and atmospheric chemistry of ambientparticulate matter. This project will build on these advances by developing arobust and autonomous instrument for chemical composition measurements,including organic and inorganic components, enabling wide-spread, long-term measurements to inform our understandingof the atmosphere. ThePhase I project successfully demonstrated the feasibility of developing anautomated calibration system using simpler, lower cost devices than the currentcalibration technique. Software developments to automate quality assurance andquality control were also demonstrated. The Phase II project will develop and field test acommercial, stand-alone calibration kit that can be used with any aerosol chemicalspeciation monitor or aerosol mass spectrometer. Additional Phase II tasksinclude further software development to automate calibration operation, anddata analysis of the aerosol chemical speciation monitor, and the developmentof new data products. Commercial Applications and Other BenefitsWe expect that the instrument developed in this program willyield a significant level of direct commercial sales and contract field measurements. The initial market for thisinstrument will be atmospheric research groups at universities and nationallaboratories with research programs focusing on atmospheric chemistry. Localand national environmental monitoringprograms constitute a potentially much larger market. |
