Understanding the Citeair index

This index has 5 levels using a scale from 0 (very low) to > 100 (very high), it is a relative estimation of the

amount of air pollution. It is based on 5 pollutants of major concern in Europe: particles (PM10), nitrogen

dioxyde (NO2), ozone (O3), carbon monoxyde (CO) and sulfur dioxyde (SO2).

This index is a background estimated index representing the overall pollution level.

Those indices have been developed under the framework of the Citeair project (Common information to

European air) and co-funded by the INTERREG IIIC and INTERREG IVC programs: Air Quality Now

The computation method for those indices, provided by Citeair, has been applied to forecast results provided

by the European pollution modelisation MACC-II.

The MACC-II (Monitoring Atmospheric Composition and Climate - Interim Implementation) is the current pre-

operational atmospheric service of the European GMES programme.

MACC-II is a Collaborative Project (2011-2014) funded by the European Union under the 7th Framework

Programme. It is coordinated by the European Centre for Medium-Range Weather Forecasts and operated by

a 36-member consortium.

The GEMS project (Global and regional Earth-system Monitoring using Satellite and in-situ data) is funded by

the European Commission within the 6th Framework Program for Research and Development under the

contract SIP4_CT-2004-516099
