Black carbon is an aerosol that is common in today’s atmosphere. In the video below, we can see the relative abundance of black carbon in South Asia over a period of three months. The dark purple regions indicate areas of lower black carbon concentrations, whereas the white areas have concentrations 20 to 40 times those of the background levels.

Notice how weather patterns move through and distribute the aerosol widely, but the source (circled in the image below) remains in place, continuing to produce more black carbon. Which of the following processes is likely responsible for the constant flux of black carbon?
