AQS Version 2.1 | The Exchange Network
Data Exchange Description
Partners can use the Exchange Network to submit data to EPA’s Air Quality System (AQS). AQS is the national database that contains ambient air quality monitoring data collected by States, Tribes, and local governments. These data are used to determine compliance with clean air standards, assess the nature of air pollution in North America, and assess the exposure of humans to airborne pollutants.
The AQS Submission schema accommodates exchanges with AQS and other Network Partners, enabling Partners to share real-time air quality data. The AQS Submission schema is compliant with the Environmental Sampling and Results (ESAR) data standard.
All data collected on or after January 1, 2015, must be submitted using v3.0. EPA is using the data collection date, rather than the submittal date, because AQS processes generally operate on a calendar year. The new schema deprecates elements that AQS will no longer allow for data collected beginning in calendar year 2015.
The Flow Implementation Guide provides a high-level overview of the data flow.
For information on how Partners have reused the AQS data exchange, see Air Quality Data Exchange and MassAir.
The Florida Department of Environmental Protection developed an AQS plugin for the Java OpenNode2. The plugin includes the ability to submit all four types of AQS data (i.e., raw data, accuracy data, precision data, and site monitor information). The plugin and implementation guide are available for download here.
