Interpolation and assimilation methods for European scale air quality assessment and mapping - Part II: Development and testing new methodologies ETC/ACC Technical Paper 2005/8

24 Dec 2005

Introduction
This paper is the second part of a project that reviews, recommends, develops and tests interpolation methods for air quality applications.

In this Part II a number of these methodologies are developed, tested and compared to established preferred methods of interpolation.

In Part I: "Review and recommendations" a literature review is carried out of methodologies that can be applied for the interpolation or assimilation of observational data to produce maps of air quality on the European scale.

Maps of air quality are important for any spatially derived assessment of air quality effects, particularly in regard to human and ecosystem exposure. As a result air quality maps, even on the European scale, will require high resolution to cover the large gradients in population and land use. In the current study emphasis is put on the development of interpolation methodologies for ozone and PM10 with the subsequent preparation of high resolution maps that can resolve urban agglomerations (in support to the Structural Indicator work of EEA to DG ENV). Ozone and PM10 as air pollutants are chosen due to their high actuality and the need for input of spatial related information on these pollutants in support to recent policy development processes (e.g. CAFE).
