New Release of U.S. EPA AERMOD, AERMET & AERMAP Models

On Jan 26th 2007, the U.S. EPA released an updated version of the AERMOD model on the SCRAM website. The AERMOD model, dated 07026, includes new features such as the special processing for PM-2.5 to calculate design values in accordance with the PM NAAQS. Beta features have also been added such as modeling options for capped stacks and horizontal releases.

The U.S. EPA also released an updated version of AERMET (06341) and AERMAP (06341) on the SCRAM website on January 18th 2007 containing several bug fixes and some enhancements. For detailed information, please see the U.S. EPA SCRAM website at:

Monthly Modeling Tip

Version in AERMET Surface Files

Every time the U.S. EPA releases a new version of AERMET and AERMOD models, the model update version number is assigned to the header of meteorological surface data file (*.SFC) pre-processed by the AERMET model. When running AERMOD, the model checks for this version number and if incompatible it gives a fatal error message as shown below. For the Jan 2007 update release of the US EPA models, AERMOD will check for the Version: 06341 or 07026. Pre-processing your surface and upper air met data files again using AERMET v. 06341 will produce new surface files containing the correct version number.

******** FATAL ERROR MESSAGES ********
ME E395 306 MEOPEN:Met. Data Error; Incompatible Version of AERMET: 04300

It is possible to directly change the version number in your existing files by opening the surface file in a text editor and modifying the version code. Before you do this, please refer to the Model Change Bulletin for the AERMET model dated 06341 to see if the latest U.S. EPA model bug fixes and changes are relevant to your case.

We recommend you pre-process your surface and upper air met data files again using the new AERMET dated 06341 to obtain the correct version number, rather than modifying your old files.
