Tools and numerical models

We are specialised in the development and adoption of numerical models for the transport and dispersion of air pollutants or odour tracers in the atmosphere.
The list of models and tools we daily use is large and comprehensive in order to adapt to the specific requirements of our customers.
We are offering solutions based on the EPA open source models such as Aermod and Calpuff.


We also use the simulation model suites AriaIndustry and AriaRegional distributed by Aria Technologies and Arianet of the SUEZ group. We perform simulations with the lagrangian particle model SPRAY, with the photochemical model FARM and with the gaussian model ARIA-Impact.

For the reconstruction of the meteorological variables we mainly use the diagnostic model SWIFT or the prognostic model WRF.

Data analysis and visualization of model outputs is performed by means of the software R [1], Python and QGIS. For these tools we have developed some free libraries. See the dedicated page to learn more.

Computational Fluid Dynamics (CFD) models of choice are ENVI-met for micro-climate studies and OpenFOAM [2] for all other cases.
