gral21 09   The Graz Lagrangian (GRAL) system is a Lagrangian particle model with a free Graphic User Interface (GUI) available in both Linux and Windows and it is well know among odour modellers. Now the developers have released the version 21.09 with plenty of bug fixes and new features.

    One more year, the GRAL GRAMM team have been working on changes and modifications in the code, and correcting bugs. This is the list of new features and bugs corrected for GRAL, GRAMM and the Graphic User Interface (GUI) for this release.

gram gral  The Graz Lagrangian (GRAL) system is a Lagrangian particle model with a free Graphic User Interface (GUI) available in both Linux and Windows. Now the developers have released the version 20.09. The software is open source under a GPL-3.0 license, so everybody is welcome to contribute to the project. The source code, has been published in github.

    The version 20.09 of GRAL GRAMM has had some changes and modifications in the code, but focusing mainly in correcting bugs. No major features have been included in this update. See a list of issues solved here. The complete source code is published under the GNU/GPL 3 licence.

 

odour exposure modelling guideline meeting   The 29th of October took place the second meeting of the group that is dealing with the new Guideline on the assessment of odour exposure by using dispersion modelling. 20 experts from around the world got in this meeting to discuss the next steps in this development. The convenors of this initiative Günther Schauberger and Jennifer Barclay presented some interesting and important points to take into account when modelling with a special focus on the peak to mean approaches.

  A set of six areas have been identified as key in dealing with odour impact modelling, that is why a set of 6 Task Groups (TG) have been defined. These are the groups:  TG1: Definitions. TG2: Meteorology. TG3: Emissions and source characterization. TG4: Dispersion algorithm. TG5. Dose-response (including P/M, hedonic tone, percentiles) and TG6. Reporting.  A Task leader have been designated for each TG.
