Fig. 3: Comparisons of biomass burning (BB) refractory black carbon (rBC) emissions, cloud condensation nuclei (CCN) concentrations, and cloud albedo forcing (CAF) using a priori and a posteriori BB emissions.
From: Improved biomass burning emissions from 1750 to 2010 using ice core records and inverse modeling
a–c Average rBC emissions during the preindustrial period (PI, 1750-1780) for (a) global, (b) North Hemisphere (NH), and (c) South Hemisphere (SH). The error bars represent the 2.5% and 97.5% range calculated by Monte Carlo simulations (Methods). d–f Average CCN concentration simulated by GEOS-Chem-TOMAS during PI (1750-1780) for global (d), NH (e), and SH (f). g–i Average CAF for PD (present day, 1997-2010) relative to PI (1750-1780) calculated by RRTMG radiative transfer model for global (g), NH (h), and SH (i).
