1850 to 2000 annual refractory black carbon depositional flux records measured in the Flade Isblink and Akademii Nauk ice cores

Black carbon is an unambiguous indicator or tracer of combustion. It is an important aerosol in Earth's radiative forcing budget and also for understanding and modeling of past and future climate. Aerosols are short-lived in the atmosphere (days to weeks), however, so arrays of measurements are required to document spatial and temporal variability in emissions, atmospheric concentrations, and radiative forcing. Records of past refractory black carbon (rBC) concentrations and depositional fluxes developed from natural archives such as ice cores and lake sediments provide information on the past. This data set includes annual rBC depositional flux records measured in ice cores collected from two lower elevation coastal times in the Arctic: Flade Isblink in northeastern Greenland and Akademii Nauk in the Russian Arctic. These records were developed using the SP2-based method on the continuous ice core analytical system at the Desert Research Institute (McConnell et al., 2007, Science; McConnell et al., 2021, Nature).
