Atmospheric chemists have been unable to explain the rapid sulfate formation observed during wintertime aerosol pollution events. Now, kinetic measurements in atmospherically relevant aerosol particles have highlighted a significant role for nitrogen dioxide in sulfate formation via its interfacial reaction with dissolved SO2.
