RE ANALYSIS Products• Surface Ensemble hourly concentrations for O3, NO2, PM10 and

PM2.5• Various air quality indicators are derived from this hourly

Ensemble :• Seasonal and annual mean surface concentrations• Number of threshold exceedances over Europe for

• PM10: daily 50µg/m3 • O3: hourly 180µg/m3 & 240 µg/m3 and daily max 8-h 120µg/m3.

• Additional air quality indicators:• AOT40 (cumulative hourly ozone concentrations above 40 ppb) - period

May – July – ppb.h• SOMO35 (yearly cumulative ozone daily max 8-hour concentrations

above 35 ppb) ppb.d• Identification of the major pollution events
