Short summary
Sources of nitrous acid (HONO), a major precursor of the OH radical, are still under controversial discussion. Since mainly ground surface sources have been proposed, HONO fluxes were measured above an agricultural field. Positive daytime fluxes were observed which showed strong correlation with the product of the NO2 concentration and J(NO2). These results indicate HONO formation by photosensitized heterogeneous conversion of NO2 on soil surfaces as observed in recent laboratory studies.
