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 XML schemas accommodate exchanges with AQS and other Network Partners, enabling Partners to share real-time air quality data. The AQS schema is compliant with the Environmental Sampling and Results (ESAR) data standard. Version 2.2a is backward compatible with v2.1 and v2.0. EPA supports submissions using all three versions.
The Flow Implementation Guide provides a high-level overview of the data flow.
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 on the OpenNode2 website.
The AQS schema and supporting flow documentation have been approved for use on the Exchange Network. The most current version is v2.2a.
