- Emission Sources Where You Live Provides state and county emission Summaries or facility emission summaries.
- AirCompare - Provides local air quality information to help you make informed, health-protective decisions about moving or vacationing.
- Air Quality Trends - Shows the pollutant levels in the air and how much is emitted from various pollution sources.
- Air Emission Sources - EPA tracks the emissions from pollutant sources.
EPA - Access EPA site for air monitoring data
EPA AQS Data Mart - Contains all air monitoring data and information from the EPA’s substance and facility registry systems.
EPA Raw Data Retrievals - Provides data back to 1993 in large compressed (ZIP) files. Use the state code "35" for New Mexico and county code "001" for Bernalillo.
Monitoring information comes from EPA's Air Quality System (AQS) database.
The data represent the best information available to EPA from state and local agencies. However, some values may be absent due to incomplete reporting, and some values subsequently may be changed due to quality assurance activities.
The AQS database is updated by state and local organizations who own and submit the data. Please contact the pertinent state or local agency to report errors.
Readers and data users are cautioned not to infer a qualitative ranking order of geographic areas based on AirData maps, charts, or reports.
Air pollution levels measured in the vicinity of a particular monitoring site may not be representative of the prevailing air quality of a county or urban area. Pollutants emitted from a particular source may have little impact on the immediate geographic area, and the amount of pollutants emitted does not indicate whether the source is complying with applicable regulations.
