A global air quality map. Real time monitoring data and forecasts of air quality that are color-coded in terms of the air quality index are available from EPA's AirNow web site. [51] Other organizations provide monitoring for members of sensitive groups such as asthmatics, children and adults over the age of 65. [52]
The PM (particulate matter) NowCast is a weighted average of hourly air monitoring data used by the United States Environmental Protection Agency (USEPA) for real-time reporting of the Air Quality Index (AQI) for PM (PM 10 - particles less than 10 micrometers, or PM 2.5 - particles less than 2.5 micrometers).
Metro areas with a population of more than 350,000 have to report air quality data on a daily basis, while other locales simply do so as a public service. ... At the time of writing, some areas of ...
Additionally, consideration of anemometer data in the area between sources and the monitor often provides insights on the source of the air contaminants recorded by an air pollution monitor. Air quality monitors are operated by citizens, [3] [4] [5] regulatory agencies, [6] [7] non-governmental organisations [8] and researchers [9] to ...
The European Environment Agency collects its air quality data from 3,500 monitoring stations across the continent. [24] The measurements made by sensors like these, which are much more accurate, are also near real-time and are used to generate air quality indexes (AQIs). Between the two extremes of large-scale static and small-scale wearable ...
A unique feature, the top of the Airmega 100 is color-coded and will changes based on what the device’s real-time Air Quality Indicator (AQI) senses: blue for good quality, green for moderate ...
