The work facilitated for the first time an integrated analysis of ozone concentrations over Ireland, including seasonal variations, trends and changes in ozone levels at 9 stations, over periods varying from 8 up to 20 years – based on the following data sources: the ground based ozone data network in Ireland – from EPA sites, from WMO Global Atmosphere Watch [GAW] sites, and from Lough Navar, Co. Fermanagh. Surface ozone data show a reduction at all sites except at Valentia Observatory and at Mace Head. Ground level ozone target levels and long-term objective ozone exceedences show a downward negative trend in peak values that affect human health and vegetation. Analysis was performed of ozonesonde columnar data from 1994 – 2009 at Valentia Observatory together with Brewer total column ozone and satellite ozone products. A regional climate model is used to assess future changes in ozone for the years 2006, 2030, 2050 and 2100.
