Special Issue Information

Dear Colleagues,

Black carbon (BC), one of the most important constituents of atmospheric pollutants, is mainly emitted by the incomplete combustion of fossil fuel and biomass/biofuels. Being absorbing in nature, it can heat the atmosphere by absorbing solar radiation and changing the surface snow albedo after deposition. It is the second-largest contributor to global climate warming after CO2 and also gained large attention among scientific communities due to its inimical impact on air quality, human health, hydrological cycle, carbon cycle and global climate change. Although ample studies have been carried out worldwide to investigate the various BC aerosol characteristics, significant uncertainties are still remaining due to the different emission sources, measurement techniques and its interactions with complex atmospheric processes. Thus, an in-depth understanding of BC characteristics and their impact on different aspects is highly needed, which will be helpful for the policymakers at the regional as well as global scale.      

This Special Issue is focused on examining the different BC characteristics and their various impacts. Original results related to BC characteristics, their source apportionment, transport mechanism, impact on air quality and climate along with review papers are all welcome as contributions.

We look forward to receiving your contributions.

Marine sediments are the ultimate reservoir for black carbon (BC) preservation, and BC burial in sediment/soils is an efficient method for carbon sequestration to mitigate CO2 emissions. A portion of soil charcoal and atmospheric BC is dissolved in inland and oceanic water, but the amount of BC in the ocean remains unclear. We analyzed multi-sediment cores from the northwestern Pacific Ocean and lakes in China and reconstructed the timeline of BC deposition from 1860 to ~2012. The lacustrine sediment cores showed an increase in BC deposition by a factor of 4–7 during the industrialization period in China compared to the years 1860–1950 (reference level). Such increasing trends in BC have also been reproduced by ten global climate model simulations. However, the marine sediment cores did not retain these significant increases in BC deposition. Meanwhile, the model simulations predicted increased trends compared to the observed flat trends of BC deposition in marine sediments. The discrepancy suggests a large amount of BC, i.e., 65 (±11)%, is missing in marine sediment sinks. Thus, since more than half of emitted BC has dissolved into oceanic water, the dissolved BC and carbon cycle should be reconsidered in the global carbon budget. Full article
