The Answers to Urbino Questions (ACCENT policy-driven synthesis report, 2006) highlighted the fact that background ozone concentrations are increasing over Europe. Measurements have shown that levels have increased by up to 5 ppbv/decade over the last 20–30 years and a similar trend is envisioned to be likely in the coming decades. Much of the focus of this increase is on the possible direct health effects of higher levels of ozone. Here, we have investigated the effects that this increase will have on in-cloud PM production. Aerosol-cloudchemistry process model simulations show that this increase in ozone will also lead to a significant increase of in-cloud sulphate production. Indeed, given such a trend by 2,100 almost 20% more sulphate mass will be produced in the simulated cloud cycle than present day.
