Organic carbon (OC) accounts for a large fraction of atmospheric aerosol and has profound
effects on air quality, atmospheric chemistry, and climate forcing. The molecular composition …

Light absorption by aerosols contributes to solar radiative forcing through absorption of solar
radiation and heating of the absorbing aerosol layer. Besides the direct radiative effect, the …

Cavity ring-down (CRD) spectroscopy is a direct absorption technique, which can be
performed with pulsed or continuous light sources and has a significantly higher sensitivity …

A new highly sensitive method for incoherent broad-band cavity-enhanced absorption
measurements of gaseous samples, using a white-light source is demonstrated. The light of …

Trapping a single aerosol particle allows detailed investigation of its fundamental properties
over extended time periods without external interferences. Optical trapping has developed …

Much of the important chemistry of the atmosphere takes place on exceedingly small
concentration scales, with principle components occurring at mixing ratios that vary from the …

Nous faisons une revue historique des méthodes de spectroscopie laser qui utilisent des
résonateurs optiques de grande finesse. La revue débute avec les premiers travaux sur …

The radiative effects of biomass‐burning aerosols on regional and global scales can be
substantial. Accurate modeling of the radiative effects of smoke aerosols requires …

Application of cavity ring down (CRD) spectrometry for measuring the optical properties of
pure and mixed laboratory-generated aerosols is presented. The extinction coefficient (α …

Elastic backscatter lidar is an established method useful to characterize the particles forming
an atmospheric aerosol. Fundamental to lidar measurements are the extinction and …
