High time resolution measurement of the OM to OC ratio in PM1 and PM2.5

Abstract : Measurements of carbonaceous aerosols are of vital importance for air quality monitoring and quantifiable measurements of climate change. Because they are extremely diverse, their direct impact on air quality, visibility, cloud nucleation and cloud optical properties, the planetary radiation balance, and public health varies greatly with composition. This impact remains highly uncertain due to their complex chemical and microphysical properties. We present here a highly time-resolved online measurement of carbonaceous aerosol species in Paris, France...
