Ion nucleation—a potential source for stratospheric aerosols

  title={Ion nucleation—a potential source for stratospheric aerosols},
  author={Frank Arnold},
The stratospheric aerosol layer is of considerable interest for its potential influence, at least temporarily, on the Earth's radiation budget and climate1. While the nature of the aerosol is now reasonably well established the mechanisms leading to the formation of new particles are poorly understood2–4. It is thought that the aerosols are formed by heterogeneous heteromolecular condensation involving sulphuric acid and water vapour and pre-existing condensation nuclei (CN) of tropospheric or… CONTINUE READING
