WebA related measure of concentration is the mass concentration ρX, representing the mass of X per unit volume of air (we will also use ρX to denote the mass density of a body, i.e., its mass per unit volume; the proper definition should be clear from the context). ρX and nX are related by the molecular weight MX (kg mol-1)ofthe gas: (1.8) WebBlack carbon (BC) is the soot-like by-product of wildfires and fossil fuel consumption, able to be carried long distances via atmospheric transport. BC comes from the burning of fossil fuels, like coal and diesel, and forest fires, and cookstoves (NASA, 2024 ). The majority reaching the Arctic comes from North America and Eurasia.
