Short summary
Short summary
Carbonate carbon (CC) is not negligible in Arctic total suspended particles (TSPs). If not considered, CC biases the contribution of elemental and organic carbon. CC content in TSPs was strongly reflected in the δ13C values of total carbon (TC). The carbon contribution from CaCO3 supports the strong dependence of CC and δ13C on Ca. Finally, two hypothetical CC sources were identified based on the analysis of air mass back trajectories: dust resuspension and marine microorganisms.

Network compatibility is important for inferring greenhouse gas fluxes at global or regional scales. This study is the first assessment of the measurement agreement among seven individual programs within the World Meteorological Organization community. It compares co-located flask air measurements at the Alert Observatory in Canada over a 17-year period. The results provide stronger confidence in the uncertainty estimation while using those datasets in various data interpretation applications.

Air pollutants, like ozone and soot, play a role in both global warming and air quality. Atmospheric models are often used to provide information to policy makers about current and future conditions under different emissions scenarios. In order to have confidence in those simulations, in this study we compare simulated air pollution from 18 state-of-the-art atmospheric models to measured air pollution in order to assess how well the models perform.

Short summary
Fires, including extreme fire seasons, and fire emissions are more common in the Arctic. A review and synthesis of current scientific literature find climate change and human activity in the north are fuelling an emerging Arctic fire regime, causing more black carbon and methane emissions within the Arctic. Uncertainties persist in characterizing future fire landscapes, and thus emissions, as well as policy-relevant challenges in understanding, monitoring, and managing Arctic fire regimes.

Short summary
Radiocarbon (14C)-based source apportionment of aerosol carbon fractions requires the physical separation of OC from EC and minimizing of the incorporation of extraneous carbon. Using pure and mixed reference materials ranging in age from modern to fossil, we show that the ECT9 protocol effectively isolates OC and EC. This work expands existing opportunities for characterizing and monitoring sources of carbonaceous aerosols, including µg C-sized samples from the Arctic.
