Air Quality Index Regions

The Air Quality Index for Health (AQIH) is comprised of 6 regions as follows: Dublin, Cork, Large Towns (>15,000), Small Towns (5,000 – 15,000), Rural East and Rural West. The AQIH is calculated on an hourly basis using representative sampling from each region. Each region is ranked 1 – 10, with 1 being ‘Good’ and 10 being ‘Very Poor’ based on the worst case pollutant in that region. Further information on the AQIH is available here http://www.epa.ie/air/quality/index/.
