Overview

Laboratory experiments show iodide boosts HONO production during nitrate photolysis, suggesting significant impacts on marine atmospheric nitrogen cycling.

Key Points

  • Iodide enhances nitrogen cycling, increasing levels of nitrogen oxides by over 25%.
  • HONO production from nitrate photolysis is boosted by over tenfold due to iodide's surface-dependent interaction.
  • Molecular simulations confirm iodide's role in reducing the solvent cage effect to promote HONO release.
  • This process significantly influences marine boundary layer chemistry, highlighting iodide's crucial role.
