RSIG3D Data Inventory

The RSIG3D application and web servers are conduits for accessing data whose quality is the responsibility of the organizations that produce and maintain the data. The organizations providing the data are linked on this page.

When a new dataset is added to RSIG3D's complement, quality checks are conducted to ensure that the data RSIG3D retrieves matches the data from the source files.

While data integrity checks have been performed by the RSIG team, not all data provided through RSIG3D has been independently quality assured by the EPA. Please direct all questions about data quality or related issues to the data source providers listed below.

Archived data may not be immediately available. Data availability depends on such factors as the remote host system's availability, the stability of network connections, and other issues beyond the control of EPA and this application. The RSIG3D application will display system messages if data is unavailable.

If a problem is noted concerning the integrity of any dataset, please contact the RSIG team.
