Air Quality System (AQS) Data Mart
The AQS Data Mart (
) is a database containing all of the information from the AQS system. The Air Quality System (AQS) is EPA's repository of ambient air quality data. AQS stores data from over 10,000 monitors, 5000 of which are currently active. State, local and tribal agencies collect the data and submit it to AQS on a periodic basis. The AQS Data Mart was built as a storehouse of air quality information that allows users to make complex, time consuming queries.
The AQS Data Mart includes information from the EPA’s substance and facility registry systems to allow for cross-media integration. It also contains the physical descriptions of monitors as the owners have entered into AQS. This includes the geographic location (latitude, longitude, elevation, and datum), the political entity where the monitor resides (tribal land or state + county), administrative information about the monitor (the agencies responsible for its operation and its schedule) and information related to the monitoring protocol: the substance (parameter) measured, the sampling method, the sampling schedule, the duration of each sample taken, the analysis method, and whether the methods are approved or equivalent reference methods.
AirData AQS REST API
The AirData AQS REST API (
) enables the retrieval of historical air quality data from EPA. AQS contains the data that the US EPA has collected via the national ambient air monitoring program. It also includes the associated aggregate values calculated by EPA (8-hour, daily, annual, etc.).
Multiple endpoints are available depending upon the operation to be performed. They are:
A synchronous request that returns raw data that matches your query criteria
Same as /rawData but performed asynchronously. A Transaction ID number is returned which can be used later to retrieve the data once the data becomes available.
The purpose of this service is to give users a "profile" of the available data in the system before they construct other queries to retrieve the data. It returns a list of monitors that match your selection criteria and a profile of the data available from those monitors. Any monitor that matches your selection criteria will be returned. Particular attention should be paid to the time window. If the monitor operated between the years of the begin date and end date (only full years are considered), the monitor will be included in the returned list. However, information about the entire operational history of the monitor will be included in the returned file.
Same as /profile but performed asynchronously. A Transaction ID number is returned which can be used later to retrieve the data once the data becomes available.
Returns the status of a previously submitted asynchronous request
Retrieves the data created with a previously submitted asynchronous request.
Returns a list of valid values for a variable.
Returns a response if the service is available
