Stable isotope measurements of carbon fractions (OC/EC) in airborne particulate: A new dimension for source characterization and apportionment
TL;DR: In this article, a method to measure 13C/12C ratios of individual carbon fractions of airborne particular matter (PM) from filter samples using a stepwise thermal desorption/combustion OC/EC analyzer (via thermal optical transmission, coupled with gas chromatography separation, followed by isotopic ratio mass spectrometer (GC-IRMS) analysis has been developed.
Journal ArticleDOI
Evaluation of a cavity ring-down spectrometer for in situ observations of 13 CO 2
TL;DR: In this article, a cavity ring-down spectrometer (CRDS) was used for continuous in situ monitoring of atmospheric 13CO2 in the range of 303-437 ppm.
Journal ArticleDOI

TL;DR: In this article, a 10-year study of continuous carbonaceous aerosol measurements collected at the Centre of Atmospheric Research Experiments (CARE) in Egbert, Ontario, Canada, on quartz-fiber filters by three independent networks (Interagency Monitoring of Protected Visual Environments, IMPROVE; Canadian Air and Precipitation Monitoring Network, CAPMoN; and Canadian Aerosol Baseline Measurement, CABM) were compared.
Journal ArticleDOI
Maintaining consistent traceability in high-precision isotope measurements of CO 2 : a way to verify atmospheric trends of δ 13 C and δ 18 O
TL;DR: In this paper, a principle and an approach for maintaining consistent traceability in high-precision isotope measurements (δ13C and δ18O) of atmospheric CO2 are described.

TL;DR: In this paper, the authors compared ten years of continuous carbonaceous aerosol measurements collected at the Centre of Atmospheric Research Experiments (CARE) in Egbert, Ontario, Canada on quartz filters by three independent networks (Interagency Monitoring of PROtected Visual Environments (IMPROVE), Canadian Air and Precipitation Monitoring Network (CAPMoN), and Canadian Aerosol Baseline Measurement (CABM)) were compared.
