cavity ringdown spectrometer in-situ measurements atmospheric trace gases
2009/2/17
This paper describes a broadband cavity ringdown spectrometer and its deployment during the 2002 North Atlantic Marine Boundary Layer Experiment (NAMBLEX) to measure ambient concentrations of NO3, N2O...
Optical properties of absorbing and non-absorbing aerosols retrieved by cavity ring down (CRD) spectroscopy
Optical property CRD spectroscopy
2008/12/4
Application of cavity ring down (CRD) spectrometry for measuring the optical properties of pure and mixed laboratory-generated aerosols is presented. The extinction coefficient (αext), extinction cros...
Extinction efficiencies of coated absorbing aerosols measured by cavity ring down aerosol spectrometry
coated absorbing aerosols cavity ring aerosol spectrometry
2008/11/3
In this study, we measure the extinction efficiency at 532 nm of absorbing aerosol particles coated with a non-absorbing solid and liquid organic shell with coating thickness varying between 5 and 100...
A compact and stable eddy covariance set-up for methane measurements using off-axis integrated cavity output spectroscopy
compact stable eddy covariance set-up methane measurements off-axis spectroscopy
2008/10/27
A Fast Methane Analyzer (FMA) is assessed for its applicability in a closed path eddy covariance field set-up in a peat meadow. The FMA uses off-axis integrated cavity output spectroscopy combined wit...
