Given the millions of people suffering from air pollution, filling the air quality monitoring gap in low- and middle-income countries has been recognized as a global challenge. To meet this challenge and make it work will require private enterprise, multiple levels of government, international organizations, academia and civil society to work together toward the common goal of characterizing, unde...

The study examines air quality in Latin American and Caribbean cities, highlighting the limited availability of comprehensive monitoring networks. It compares surface measurements with data from CAMSRA and Tropomi satellites, revealing persistent air pollution issues exceeding WHO guidelines for particulate matter. The findings underscore the potential of global monitoring systems to provide cruci...

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....

The document describes the latest WHO database on ambient air quality. The guidelines recommend new air quality levels to protect the health of populations. Moreover reducing the levels of key air pollutants will also contribute to slowing climate change. Pollutants for which new guidelines for annual mean values have been set are PM2.5, with a guideline value half the previous one, PM10, which is...

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, ...

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....

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...

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...

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 ...

This JRC Reference Report on Monitoring (ROM) summarises information on the monitoring of emissions to air and water from IED installations, thereby providing practical guidance for the application of the Best Available Techniques (BAT) conclusions on monitoring in order to help competent authorities to define monitoring requirements in the permits of IED installations....
