Air Data

Air Data is the best way for the public, researchers, and governmental agencies to access our air quality from any state, local, or tribal air quality agency. Data is typically valid and certified by the middle of the current year for the year prior. This means that all 2018 data from all agencies will be certified by May 1, 2019.
