Methodological improvements on interpolating European air quality maps ETC/ACC Technical Paper 2009/16

Iulian Petchesi

The paper comes to the following main recommendations: keep using the current interpolation method with the separate rural, urban and joint rural/urban maps on just the 10x10 km grid resolution; implement log-normal transposition of PM10 concentrations (not for ozone); when Corine Land Cover covers the European mapping domain, reconsider for PM10 introducing certain land use classes; apply refined merging criteria related to the rural and urban area classification; implement merging on a finer resolution (1x1 km instead of 10x10 km grids) as most important improvement; never aggregate concentration maps for health exposure estimates.
