Source apportionment of circum-Arctic atmospheric black carbon from isotopes and modeling

|
By T. E. Barrett, R. J. Sheesley, L. Huang, P. Winiger
| Science Magazine Verified
Abstract Black carbon (BC) contributes to Arctic climate warming, yet source attributions are inaccurate due to lacking observational constraints and uncertainties in emission inventories. Year-round, isotope-constrained observations reveal strong seasonal variations in BC sources with a consistent and synchronous pattern at all Arctic sites. These sources were dominated by emissions from fossil fuel combustion in the winter and by biomass burning in the summer.

Year-round optical properties and source characterization of Arctic organic carbon aerosols on the North Slope Alaska

| Color Research & Application Verified
Long-term data on organic aerosol concentration and optical properties is needed in the Arctic to improve characterization of radiative forcing by atmospheric aerosols. This study presents the seasonal trends (summer 2012- summer 2013) of organic carbon (OC) and water-soluble organic carbon (WSOC) along with optical properties of light-absorbing OC from a year-long sampling campaign in Utqia?vik, AK.

Evaluation of ground-based black carbon measurements by filter-based photometers at two Arctic sites

Long-term measurements of the light absorption coefficient (b ) obtained with a particle soot absorption photometer (PSAP), b (PSAP), have been previously reported for Barrow, Alaska, and Ny-Ålesund, Spitsbergen, in the Arctic. However, the effects on b of other aerosol chemical species co-existing with black carbon (BC) have not been critically evaluated. Furthermore, different mass absorption cross section (MAC) values have been used to convert b to BC mass concentration (M ?=?b /MAC).
