Reconstructed Black Carbon Emissions from 1750 to 2010 using Ice Core Records and Inverse modeling

This dataset contains two sets of gridded emissions of black carbon (BC) from 1750 to 2010, i.e., BB4CMIPpost on 0.25°×0.25° grid and LPJ-LMfirepost on 0.5°×0.5° grid. The new emission datasets are derived by inverse analysis that leveraged a global array of 31 ice core records of BC deposition fluxes, existing emission inventories as a priori estimates (BB4CMIP+CEDS for BB4CMIPpost, LPJ-LMfire+CEDS for LPJ-LMfirepost), and emission-deposition sensitivity simulated by chemical transport model GEOS-Chem. BB4CMIP is a historical biomass burning dataset based on satellite-based dataset (GFED4) after 1997, fire model results from FireMIP before the satellite era, and existing observational proxies (such as charcoal records and visibility observations) if available. LPJ-LMfire is a dynamic global vegetation model coupled with a fire module, with consideration of human influences on fire by hunter-gatherers, pastoralists, and farmers. CEDS is a historical emission dataset from anthropogenic fossil fuel and biofuel combustion. \\ Ref of BB4CMIP:van Marle MJE, et al.
