Latest update : Mapping Manual

The version of chapter 5 of the Mapping manual, which was adopted by the Working Group on Effect at the 2nd joint session of the EMEP Steering Body and the Working Group on Effects (Geneva, 13-16 September 2016) is now available

Manual on Methodologies and Criteria for Modelling and Mapping Critical Loads and Levels and Air Pollution Effects, Risks and Trends.

This manual describes methods for calculating critical loads and levels, as well as for dynamic modelling to be used by National Focal Centres (NFCs) of the LRTAP Convention. It provides harmonised indicators to assess the impacts of acidification, eutrophication, ozone and particulate matter on terrestrial and aquatic ecosystems, crops or building materials. These indicators result from 35 years of scientific research, in close collaboration with policy makers to answer the needs of policy development and implementations.

The Chapters of the Mapping Manual can be downloaded from this page right column.


Updates of the Mapping Manual

The First Mapping Manual was published in 1993. In order to keep up with new scientific findings, the Mapping Manual has been updated in 1996 and 2004 and again in 2016, following an invitation to ICP M&M by the WGE in September 2013 (document ECE/EB.AIR/WG.1/2013/2). This last update was lead by the ICP M&M chair with the contributions of the CCE and NIVA for Chapters 1, 2 and 5 to 8. Chapter 3 was updated and reviewed by ICP Vegetation and its Task Force, while Chapter 4 was updated and reviewed by ICP Materials and its Task Forces. Chapter 5 is still currently under review. This update has been funded by Germany and France.

In the future, each chapter will be updated independently to reflect new scientific knowledge.

Each chapter is to be quoted as: “ CLRTAP, 2014. Guidance on mapping concentrations levels and deposition levels, Chapter [chapter number] of Manual on methodologies and criteria for modelling and mapping critical loads and levels and air pollution effects, risks and trends. UNECE Convention on Long-range Transboundary Air Pollution; accessed on [date of consultation] at www.icpmapping.org”.
