Short summary

We investigated why reactive bromine increases in the Arctic atmosphere during spring. Using observations in Ny-Ålesund and modeling. We found that BrO increases are strongly linked to airborne particles and bromine emissions from snow over sea ice. Both snow over first-year and multi-year sea ice contribute comparably. These processes are enhanced by strong winds and drive depletion of surface ozone and mercury.
