24 Jul 2014Running latest version of AERMOD from ADMS 5

ADMS 5 includes a facility to run the main model options of AERMOD from the ADMS 5 interface. Since the release of ADMS 5 SP1 (April 2013) the US-EPA have released two new versions of AERMOD and AERMET:

  • version 13350 (December 2013) - this version can be run from ADMS 5, see helpdesk note 101 for further details on how to update to this version of AERMOD and AERMET,
  • version 14134 (May 2014) - CERC have discovered an issue with this version of AERMOD if receptor points are very close to a source. We are currently in discussions with the US-EPA on the best method of resolving this issue, as such it is not currently possible to use this version with ADMS 5.

If you need help in updating to version 13350 or have any further questions on the issue then please contact the helpdesk.

8 Jul 2014New EFT versions released (6.0 and 6.0.1)

Two new versions of Defra's Emission Factor Toolkit have been released recently. Version 6.0 was released in June 2014, followed by version 6.0.1 (containing some bug fixes) at the beginning of July 2014. The EFT can be downloaded from the following webpage:


Details of the updates included in these latest releases are summarised on page 4 of the EFT User Guide, which is also downloadable from the location given above.

ADMS-Urban, ADMS-Roads and ADMS-Airport incorporate the EFT emission factors so that emission rates can be calculated from available traffic and speed data. CERC consider giving users access to the latest emission factors a high priority. We are currently working on compiling a model update that includes the EFT version 6.0.1 emissions factors. At the very latest, this update will be available to users with current support by the middle of September.
