In January 2018, an EPA Data Validation Workgroup formed with a goal to develop a tool that could be used to assist personnel in any state, local, or tribal (SLT) monitoring organization with performing data review and validation techniques. This report in • Section 1.2 provides the basis for the data review requirements, including data quality regulations and supporting fundamentals. • Section 2 ...

The Asian Development Bank (ADB) and Clean Air Asia carried out Air Quality Interventions: Improving Air Quality Monitoring Systems in Asian Cities project (Sub-Project of RETA 6422: Mainstreaming Environment for Poverty Reduction) which focuses on improving AQ monitoring systems in the region and enhancing technical collaboration among Asian cities. The Sub-Project supported the assessment of air...

The document provides an overview of air quality issues in Latin America, highlighting sources of pollution, health impacts, and regional initiatives to improve air quality management. It emphasizes the need for integrated strategies involving policy development, technological advancements, and public awareness campaigns to address the complex challenges of air pollution across Latin American coun...

Collecting air quality data is crucial for evidence-informed measures to reduce air pollution. But the systems used to manage this data bring numerous challenges to governments and organisations. An open-source system developed by the global clean air movement would enable smarter and cheaper data management across the world....

Low-cost air quality sensor systems (LCS) are emerging technologies for policy-relevant air quality analysis, including pollution levels, source identification, and forecasting. This report discusses LCS use in networks and alongside other data sources for comprehensive air quality applications, complementing other WMO publications on LCS operating principles, calibration, performance assessment, ...

The WHO Air Pollution Data Portal provides data on exposure levels and health impacts (i.e. deaths, DALYs) of air pollution at the national, regional and global level from ambient (outdoor) and household air pollution. Such estimates are used for official reporting like the world health statistics, and the Sustainable Development Goals....

In partnership with IQAir, UNEP hosts the world's largest databank for fine particulate matter PM 2.5. i.e. particulate matter with diameters that are generally 2.5 micrometers and smaller in size. This database is an example of the potential of crowdsourcing air pollution data. It provides an interactive map that shows real-time estimates for PM2.5 from thousands of governments, researchers, and ...

AirNow DOS collects Air Quality Monitoring data from U.S. embassies and consulates around the world to inform U.S. personnel and citizens overseas....

The co-operative programme for monitoring and evaluation of the long-range transmission of air pollutants in Europe (inofficially 'European Monitoring and Evaluation Programme' EMEP) is a scientifically based and policy driven programme under the Convention on Long-range Transboundary Air Pollution (CLRTAP) for international co-operation to solve transboundary air pollution problems. Five EMEP Cen...

To address the current gaps in knowledge of global PM2.5 concentrations, the Surface Particulate Matter Network (SPARTAN) hosted at Washington University in St. Louis, MO, United States is working to measure fine particulate concentrations to evaluate and enhance satellite remote sensing estimates of PM2.5. The network provides publicly available data on PM2.5 mass, chemical composition, and optic...
