TL;DR: In this paper, the authors conducted a comprehensive intercomparison of this type (multimethod, multilab, and multisample), focusing mainly on methods used for soil and sediment BC studies.

TL;DR: In this paper, a series of laboratory studies of photochemical processing of aerosol brown carbon in the aqueous phase, by direct photolysis and OH oxidation, was reported. And the results indicated that atmospheric models need to incorporate representations of atmospheric processing of BrC species to accurately model their radiative impacts.

TL;DR: In this paper, the authors evaluated sulfate and black carbon (BC) concentrations from eleven different models driven with the same emission inventory against a comprehensive pan-Arctic measurement data set over a time period of 2 years (2008-2009).

TL;DR: In this article, a method to measure 13C/12C ratios of individual carbon fractions of airborne particular matter (PM) from filter samples using a stepwise thermal desorption/combustion OC/EC analyzer (via thermal optical transmission, coupled with gas chromatography separation, followed by isotopic ratio mass spectrometer (GC-IRMS) analysis has been developed.

TL;DR: One year of aerosol particle observations from Alert, Nunavut shows that new particle formation (NPF) is common during clean periods of the summertime Arctic associated with low condensation sinks and with the presence of methane sulfonic acid (MSA), a product of the atmospheric oxidation of dimethyl sulfide (DMS).
