Guidance for Air Dispersion Modeling

Information for Air Dispersion Modeling.

 

Guidance for Air Dispersion Modeling – TCEQ Air Quality Modeling Guidelines coming soon.

Off Property Source Inventory

The TCEQ has replaced the Point Source Database (PSDB) with the Air Permits Allowable Database (APAD) as the data source for generating modeling retrievals. The new procedure to request modeling retrievals is similar to the previous one, but there are some minor differences. Please refer to the guidance outlined in the How to Request Modeling Retrieval on how to submit the Modeling Request Form. Additional information on the retrieval can be found in the Modeling Request Fact Sheet.

Monitoring Data

Elevation Data

National Elevation Dataset (NED) terrain data can be obtained as a GeoTIFF to use in AERMAP from the Multi-Resolution Land Characteristics Consortium (MRLC). Exit the TCEQ

How to download NED data as a GeoTIFF from the MRLC Consortium Viewer:

    1. Click the “Data” button (located in the top right corner of your browser)
    2. Click “Download Tool”
    3. Click “Define Download Area by Coordinates” button
    4. After the boundaries are submitted, click on “Modify Request” in order to download the NED data as a GeoTIFF
