Something in the Air Reports

A series of reports highlighting the promising potential of satellite data to complement and enhance the United States’ existing air quality monitoring network.

As a nation, we make great strides cleaning up air pollution—but not all communities benefit equally.

For 25 years, the American Lung Association’s “State of the Air” report has helped people across the country understand the quality of the air in their communities. Using data from a national network of official regulatory monitors, “State of the Air” reports on levels of ozone and particulate pollution in counties and metro areas. The “Something in the Air” reports build on that history of success by showcasing ways in which emerging technologies, such as satellites, can be used to enhance the air quality information available to all communities, from rural areas with no regulatory monitors to urban neighborhoods disproportionately exposed to roadway and industrial pollution.
