The document provides a comprehensive study on air quality, focusing on atmospheric composition, pollutants, their sources, and health effects. It includes methodologies for monitoring air pollutants, meteorological fundamentals of pollutant dispersion, air quality modeling, indoor air pollution, and management strategies for air quality assessment. The document aims to enhance environmental scien...

The assessment report summarizes the existing scientific knowledge on transboundary air pollution issues within the North America region and describes effectiveness of air pollution measures across different sectors....

This assessment report summarises current scientific knowledge on transboundary air pollution issues within the UNECE region and describes the effectiveness of air pollution measures in addressing large-scale effects on forests and lakes as well as in protecting human health and preventing other air pollution effects, such as loss in biodiversity and damage to crops, the built environment and cult...

The UNEP Pollution Action Note displays the global state of air pollution, major sources, the impact on human health, and national efforts to tackle this critical issue....

This report is designed for a specific group of decision and policymakers whose functions encompass establishing the legal and regulatory framework for AQM, clean air action planning, championing air quality improvement and mitigation of climate change impacts and gaining support from national government agencies and development organizations for AQM....

The document provides a comprehensive framework for understanding and deploying innovation and partnership models that inform, evaluate, and build sustained support for local, regional, and national clean air measures. The guide is mainly intended for government officials, technical partners, and other stakeholders in cities and metropolitan areas with limited local air quality management capacity...

The ICP Vegetation Task Force (International Cooperative Programme on Effects of Air Pollution on Natural Vegetation and Crops) is a working group under the UNECE/CLRTAP. The Scientific Background Document B contains DO3SE model parameterisations for additional species and information on developing areas of ozone research and the application of methodologies to further develop ozone critical level...

The ICP Vegetation Task Force (International Cooperative Programme on Effects of Air Pollution on Natural Vegetation and Crops) is a working group under the UNECE/CLRTAP. The purpose of this chapter is to provide information on the critical levels of air pollutants for vegetation and the methodology for calculating critical level exceedance....

The ICP IM Task Force (International Co-Operative Programme on Integrated Monitoring of Air Pollution Effects on Ecosystems) is a working group under the UNECE/CLRTAP. Integrated monitoring of ecosystems means physical, chemical, and biological measurements. Different measurements are made simultaneously in a defined area. This is done continuously and forms a consistent time series. For the measu...

The OSVALD (Ozone Symptom VALidation Database) is an on-line validation tool for ozone visible injury on wood species, developed by the ICP Forests Task Force, a working group under the UNECE/CLRTAP....
