Short summary

We present spatial measurements of particle volatility and mixing state near a US interstate highway. We find that the relative abundance of semi-volatile species in ultrafine particles decreases with downwind distance and the mixing state of roadside aerosols does not change significantly within a few hundred meters from the highway. The results from our study show that exposures and impacts of near-road particles may differ across seasons and under changing ambient conditions.
