Black carbon (rBC), bismuth, lead and others from 1741 to 2015 AD from Colle Gnifetti ice core (Swiss/Italian Alps)

We present sub-annually resolved concentration records of refractory black carbon (rBC; using soot photometry) as well as distinctive tracers for mineral dust (calcium, sulfate, sodium), biomass burning (ammonium) and industrial pollution (lead, bismuth, ammonium, nitrate) from the Colle Gnifetti (4450 m asl; 45.932°N, 7.876°E) ice core in the Alps from 1741-2015 AD. The data is a composite of two ice cores: CG03B drilled in 2003; CG15 drilled in 2015 at the same site.
