Released version 20.09 of GRAL GRAMM

on .

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.

2nd meeting of the group developing a new guideline on odour exposure modelling

on .

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.

Successful kickoff meeting for the new guideline on assessment of odour exposure by using dispersion modelling

on .

first meetingThe 27th of August 2020 took place the kickoff meeting of the group dealing with the development of the first international guideline on the assessment of odour exposure by using dispersion modelling. To date, there are already 36 professionals from Belgium, Italy, France, Chile, Ecuador, Australia, Brazil, United Kingdom, Ireland, China, Spain, USA, India, Peru, Qatar and Austria participating in this initiative.

   This development is being led by Dr. Günther Schauberger, professor of the University of Veterinary Medicine of Vienna,  and Ms. Jennifer Barclay, principal scientist of Atmospheric Science Global (ASG) in New Zealand. The list of volunteers in this initiative at this stage is the following:
