Besides the homogeneous reaction of NO with OH, four ad- ditional HONO sources are considered in the WRF-CHEM model: secondary HONO formation from NO 2 heteroge- neous reaction

Within this context, the objectives of HIBISCUS were to provide a set of new observational data on meteorology, trac- ers of horizontal and vertical transport, water vapour, clouds,

Although the WRF-CHEM model follows well the variation of OH concentrations, it underestimates the OH concentrations in the late morning and early afternoon, regardless of whether
