This PowerPoint serves as a template presentation which introduces topics related to air quality and is part of a suite of presentations provided by the EPA for the Megacities program....

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...

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 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...

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...

This article proposes an air quality measurement and analysis system (AQMAS) framework as a systematic and comprehensive approach to guide the efforts of LMICs to put in place the key activities and actors to underpin the development of the knowledge base regarding the state of air pollution and use this knowledge to address air pollution....

This paper presents a dataset of air quality observations collected from 68 spatially distributed monitoring stations across Uganda. The dataset includes hourly PM2.5 and PM10 data collected from low-cost air quality monitoring devices and one reference grade monitoring device over a period ranging from 2019 to 2020. This dataset contributes towards filling some of the data gaps witnessed over the...

The article examines the evolution of air quality monitoring networks in cities, particularly focusing on Bogota as a case study. It highlights how these networks initially emerged in Latin America during the 1960s, driven by international power dynamics rather than local pollution concerns. Despite their controversial beginnings, these monitoring systems eventually became crucial for public healt...

Air pollution is defined as a phenomenon harmful to the ecological system and the normal conditions of human existence and development when some substances in the atmosphere exceed a certain concentration. In the face of increasingly serious environmental pollution problems, scholars have conducted a significant quantity of related research, and in those studies, the forecasting of air pollution h...

The article discusses the emergence of low-cost sensors as viable alternatives to traditional air quality monitoring equipment since 2013. These sensors are commercially available with diverse operating principles, but standardization and calibration methods are still in development. The selection of sensors depends on the variables of interest, facilitating adaptation to commercial availability, ...
