Abstract. Brown carbon (BrC) absorbs solar radiation, thereby partially offsetting the cooling effect of aerosols on the climate. However, its contribution to climate forcing remains poorly constrained and is currently not explicitly included in the overall radiative forcing estimates of the IPCC. …

Abstract. Aerosols play a critical role in Earth’s climate, but substantial evolution in their physicochemical properties after emission introduces uncertainties in predicting their climate impacts. Observational constraints on how aging modifies aerosol properties remain limited. Here, we investigate the effects of ~2–6 …

A 2-year intercomparison of three methods for measuring black carbon concentration at a high-altitude research station in Europe

Sarah Tinorua, Cyrielle Denjean, Pierre Nabat, Véronique Pont et autres

Black carbon (BC) is one of the most important climate forcers with severe health effects. Large uncertainties in radiative forcing estimation and health impact assessment arise from the fact that there is no standardized method to measure BC mass concentration. This study …
