Short summary
The contribution of fossil and non-fossil carbon sources to aerosols sampled in the Arve River valley is quantified with 14C measured by AMS with a CO2 gas source. Results show a high contribution of non-fossil carbon sources during winter, which is highly correlated to levoglucosan concentration, showing that almost all of the non-fossil carbon originates from wood combustion. This correlation is also used to separate the contributions of wood burning and biogenic emissions for summer samples.
