Sammendrag
To assist in producing spatial maps of NO2 concentrations this report details methodologies for creating such maps in a cost effective way, with the use of passive samplers. It provides an overview of passive sampling methods in regard to their costs and quality. It then provides a statistical assessment of the uncertainty in converting limitedpassive sampler measurements to annual mean and percentile concentrations, based on an analysis of measurement data available in Nordic countries. This is discussed in relation to the European air quality directives. It then reviews the current state-of-the-art in air quality mapping using both passive samplers and other data sources. Finally it describes and recommends different mapping methodologies.
