Air pollution maps, also known as air quality maps, are visual representations that depict the levels of air pollution in specific geographical areas. These maps provide valuable information about the distribution and severity of various pollutants, such as particulate matter (PM), nitrogen dioxide (NO2), ozone (O3), and sulfur dioxide (SO2), among others.
Air pollution maps are created by collecting data from monitoring stations strategically placed across different regions. These monitoring stations measure pollutant concentrations at specific intervals, allowing for the creation of a comprehensive picture of air quality in a given area.
The collected data is then processed and transformed into color-coded or gradient maps that indicate pollution levels. Typically, colors such as green, yellow, orange, and red are used to represent different air quality categories, ranging from good to hazardous. These maps can be interactive, enabling users to zoom in, explore specific locations, and obtain real-time or historical air quality information.
