Sources of Nitrous Acid in the Atmospheric Boundary Layer

Nitrous acid (HONO) is a minor air pollutant, but plays a major role as a key precursor to the OH radical in the continental boundary layer.  OH in turn initiates most atmospheric chemical processes, removing primary pollutants and forming secondary species.

Our work aims to quantify sources of HONO: Direct emission from vehicle traffic (investigated through road tunnel experiments); production by soil bacteria (studied through flux measurements) and renoxification on aerosol particles in the marine boundary later at the Cape Verde observatory (pictured).

This work is funded by the NERC, and is a collaboration with the Universities of Leicester, York and CEH.
