For the fifth consecutive year, the U.S. Environmental Protection Agency (EPA) has released data showing improvements in air quality across the nation. According to the data, air quality in the United States in 2022 improved from the previous year, with a 5 percent decrease in levels of fine particles and a 3 percent decrease in ozone pollution.
The EPA's air quality rankings are based on data collected through the Air Quality Index (AQI). The AQI is a scale that measures the concentration of pollutants in the air on a daily basis. It uses a color-coded system to indicate the amount of pollution present in the air, with “good” air quality falling within the green range and “unhealthy” air quality falling within the red range.
To get a better understanding of the data, NBC News has created an interactive map that allows users to explore air quality in their city or state. By entering a city or state name in the search bar, users can view detailed information about air quality in their area. The map also offers a visual representation of the data, allowing users to compare air quality in different parts of the country.
Overall, the data shows that air quality across the United States improved in 2022. While certain cities and states saw more dramatic improvements than others, the data suggests that the nation is on the right track towards improving air quality.
For those interested in learning more about the air quality in their area, this interactive map from NBC News offers a comprehensive look at the data. By exploring the data, users can get a better understanding of air quality improvements in their area and how their city or state fared in 2022.
