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...

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...

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...

With the increasing development of microsensors technology, Airparif (the independent regional air quality observatory for the greater Paris region) and AIRLAB (its open innovation laboratory) periodically organise the AIRLAB Microsensors Challenge. This event aims to provide a robust and independent evaluation of the performance of microsensors, under real conditions of use in order to provide a ...

AirQo analytics allows users to have access to real-time and historic air quality information across Africa through an interactive dashboard....

EANET is an intergovernmental initiative including 13 countries in East Asia formed to create a common understanding of the state of acid deposition problems in the region. It also monitors air pollution and produce high-quality open data. Major Measurements include: Gases: concentrations of sulfur dioxide (SO2), nitrogen oxides (NO, NO2), ozone (O3), nitric acid (HNO3), hydrogen chloride (HCl), a...

The application allows users to intercompare historic, near real-time satellite observations, ground-based air quality observations, and forecasted conditions to assess how well they intercompare and perform. This ability enables partners such as the Pollution Control Department (PCD), Geo-Informatics & Space Technology Development Agency (GISTDA) as well as decision-makers to leverage satellite o...

sensors.AFRICA is a pan-African citizen science initiative that uses sensors to monitor air, water and sound pollution to give citizens actionable information about their cities....

The Tropospheric Ozone Assessment Report (TOAR) is an international activity under the International Global Atmospheric Chemistry project. It aims to assess the global distribution and trends of tropospheric ozone and to provide data that are useful for the analysis of ozone impacts on health, vegetation, and climate. The TOAR data centre collects information about available tropospheric ozone dat...

The BreatheLife platform shows air quality conditions in different cities across the globe. It combines ground station monitoring with satellite data for a comprehensive view of air pollution levels in over 4,000 cities and its impacts on health ain every country in the world....
