In fact, existing pollutant information is often not readily available to the public—an important stakeholder for mitigating health and environmental impacts of air pollution.With millions of users accessing the platform, both individuals and government institutions can use real-time air quality measurements to track local pollution levels, receive customized health recommendation—via the platform or a mobile app—and view commitments to improve air quality from cities around the world.The platform currently receives real-time data from more than 4,000 providers (including governments) and has a following of more than 15 million users.“Providing real-time data in a simple-to-understand format at this scale is an important step UNEP is taking to fill the data gap,” says Sean Khan, a UNEP expert on air and global environment monitoring systems.“We expect this dataset to grow following the launch and use cases of successes and contributions to the platform to inspire replication. Users can visualize imagery related to Air Quality in Worldview or download data using the links below. The Air Quality application shows the real-Time Air Quality Index (AQI) for more than 60 countries in the World (Mainland China, Hong Kong, Taiwan, Singapore, Vietnam, India, Malaysia, Thailand, South Korea and Japan....) The Air Quality data sources varies depending on the cities: - The US Embassy PM2.5 data is used for Shanghai, Beijing, Chengdu and Guangzhou. According to the World Health Organization Indoor air pollution takes a particularly heavy toll on women and young children, as they are most likely to stay indoors for longer periods of time, where they are exposed to the fumes from cooking and heating.

Those four countries regularly come in near the bottom of annual rankings for air quality. The fire layer is useful for studying the spatial and temporal distribution of fire, to locate persistent hot spots such as volcanoes and gas flares, to locate the source of air pollution from smoke that may have adverse human health impacts.

Aerosols scatter and absorb incoming sunlight, which reduces visibility. AirVisual Earth covers pollution airflows across the world by combining PM2.5 data from public government air quality stations, satellite data and our community From an observer on the ground, an AOD of less than 0.1 is “clean” - characteristic of clear blue sky, bright sun and maximum visibility. These measurements are useful for analyzing the distribution, transport, sources and sinks of CO in the troposphere and can be used to observe how it interacts with land and ocean biospheres. Accurate early warnings of poor air quality are useful because they give people the option to reduce their risk of exposure to poor air by limiting outdoor activity at these times.

Provides real-time air pollution data in an understandable, visual format, information about the public health and environmental effects of air pollution, information about ways in which the public can protect their health, and actions they can take to reduce pollution. Aerosols have an effect on human health, weather and the climate. Air quality forecasters use near real-time data from NASA's Land, Atmosphere Near real-time Capability for EOS to improve some local and national air quality forecasts.

As described an article from NASA's Earth Observatory - Aerosols compromise human health when inhaled by people with asthma or other respiratory illnesses. The exposure to polluted air seems almost impossible to escape. The good news is that Bangkok has more monitors reporting real-time air quality data than any other city in the world: more than 1,000. The MODIS Fire and Thermal Anomalies product is available from the Terra (MOD14) and Aqua (MYD14) satellites as well as a combined Terra and Aqua (MCD14) satellite product. The Measurements of Pollution in the Troposphere (MOPITT) Carbon Monoxide (Level 2, Daily, Day/Night, Total Column) layer shows the amount of carbon monoxide (CO) present in the total vertical column of the lower atmosphere (troposphere) and is measured in mole per square centimeter (mol/cm2) for the Day and Night overpasses, in near real-time (NRT). MOPITT NRT measurements use thermal-infrared radiation at 4.7 µm to produce CO total column abundance. The Atmospheric Infrared Sounder (AIRS) Carbon Monoxide (CO) Total Column (Day/Night) layer indicates the amount of Carbon Monoxide (CO) in the total vertical column profile of the atmosphere (from Earth’s surface to top-of-atmosphere) and is measured in parts per billion by volume (ppbv).The imagery resolution is 2 km and sensor resolution is 45 km. Map layers include: CO is a trace gas produced by methane oxidation, fossil fuel consumption (emitted from factories and cars) and biomass burning (from forest fires and agricultural burning).
