First draft of the International Handbook on the Assessment of Odour Exposure by using Dispersion Modelling

There is no translation available.

   TodayFirst draft handbook, the over 50 volunteers that are working on the first International Handbook on the Assessment of Odour Exposure by using Dispersion Modelling reached their first milestone. The first draft of this handbook, was just released (only available for the volunteers) and it has, at this stage, 289 pages of information on the topic.

   The group has had already 20 monthly meetings since the very first meeting took place the 27th of August 2020. This development is being led by Ms. Jennifer Barclay, principal scientist of Atmospheric Science Global (ASG) in New Zealand and Dr. Günther Schauberger, professor of the University of Veterinary Medicine of Vienna, Austria.

GRAL 24.04 Update: Key Fixes and Enhancements

There is no translation available.

   The latest version of the GRAL dispersion model, 24.04, has been released and it includes several updates and bug fixes. GRAL, a Lagrangian dispersion model, is extensively used for simulating pollutant dispersion, and these updates are expected to enhance its reliability in various environmental scenarios.

   A significant fix in version 24.04 addresses an issue that caused incorrect concentration calculations within buildings. This bug, present since version 23.11, affected flat terrain and certain building configurations. Correcting this issue ensures that GRAL can provide more accurate simulations in urban settings where building interactions play an important role.

GRAL Dispersion Model has a new website

There is no translation available.

   Since this month November 2022, GRAL dispersion model presents a new website: https://gral.tugraz.at/ The Graz Lagrangian Model - GRAL - was initially developed in 1999 at the Institute of Thermodynamics and Sustainable Propulsion Systems at Graz University of Technology.

   In addition, new features and bugfixes have been implemented in the new GRAL Version 22.09, which is now available on the GRAL homepage.
