Enviroware, an Italian company specialised in air quality consulting, has released version 7.2.1 of its EW_CALPUFF, a graphical user interface (GUI) dedicated to easily manage the Lagrangian puff model CALPUFF, widely used in atmospheric dispersion modelling for pollutants and odours.
If you work with odour modelling, you are probably familiar with the dispersion model CALPUFF. This is a propietary, source-available (not open-source) non-steady-state Lagrangian puff model used to simulate pollutant transport, transformation, and deposition, taking into account time- and space-varying meteorological conditions. The official proprietary software (not open-source) CALPUFF core models (CALMET, CALPUFF, and CALPOST) are free to download and can be run via the command line, although the GUI requires a paid licence. In the past, there were several other GUIs available, such as CALPro, CALApps, Beeline, or MMS-CALPUFF but most of these have now been discontinued. Another well-known GUI is this one of the Italian company Enviroware that has been recently updated. This release introduces two new features.
- Batch File Creation and External CALPUFF Execution: A key addition is the ability to generate batch files and launch CALPUFF externally from within the interface. This allows users to run multiple simulations in parallel, significantly reducing computation times for complex scenarios.
- Wind Roses from CALMET Data: This new version of EW_CALPUFF can now directly produce wind roses using meteorological data extracted from CALMET outputs. These visualisations enhance the analysis of wind patterns, providing deeper insight into pollutant dispersion pathways.
EW_CALPUFF simplifies input management, data validation, and post-processing of results. It integrates seamlessly with CALMET for global modelling domains, making it ideal for regulatory compliance and environmental consulting in odour control. Download a free trial version here.
