South Coast AQMD’s AQ-SPEC program aims at being the testing center for low cost air monitoring sensors to establish performance standards by which sensors are evaluated. The program evaluates sensors in the field, under ambient conditions, and in the laboratory under controlled environmental conditions for sensors measuring criteria pollutants (PM2.5, PM10, NO2, ozone, carbon monoxide) and volati...

JAXA estimates the quantities and types of aerosols by using domestic and international satellite data in multiple way and provides obtained information to both research institutes and other users. Also, JAXA conducts research development for incorporating measured satellite data into computer simulations of aerosol transport models (data assimilation) in accordance with external institutions. The...

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...

NASA satellites continually orbit the globe, collecting information about Earth’s ocean, atmosphere, and land surfaces. Satellites can even monitor the activity of life forms, such as phytoplankton, from their remote vantage points. Satellite imagery provides the greatest benefit to the most people when it can be analyzed by anyone with an interest. NEO strives to make global satellite imagery as ...

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...

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

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 ...

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....

The Standard Operating Procedure (SOP) for the Teledyne API Model T640 PM Mass Monitor was developed through a collaboration between Sonoma Technology, Inc., the EPA, and multiple monitoring agencies. It incorporates feedback from user experiences and various experts, with revisions influenced by a broad range of contributors. The document aims to aid agencies in effectively using the T640x monito...

The webpage on the EPA's site provides detailed information and resources on continuous monitoring of PM2.5, a fine particulate matter, for air quality assessment. It includes guidance documents, tools for data assessment, standard operating procedures, technical systems audit checklists, and information on policy and data management. These resources support the implementation and maintenance of P...
