Short summary

Water-soluble pyrogenic carbon (WSPyC) in the ocean is the ultimate sink for WSPyC, but its budget has not yet been fully quantified. This study observed the variations in the concentration of WSPyC in atmospheric aerosols in Sapporo, Hokkaido, over the course of a year, and examined its sources. The results suggest that WSPyC can be formed through the oxidation of soot during atmospheric transport, highlighting the need to reassess the global deposition flux of WSPyC.
