Short summary
HONO is a large source of OH radicals, which can drive VOC oxidation, leading to the formation of ozone and secondary organic aerosols. Here we investigate primary vehicle emissions of HONO from measurements in a road tunnel in Birmingham, UK. A HONO/NOx emission ratio was detemined and compared to previous studies. Results indicate HONO/NOx has not varied much over the last two decades and technologies aimed at reducing NO2 may have also resulted in a reduction in direct HONO vehicle emissions.
