Software for Reconstructing the Atmospheric Impact of Pollutants Emitted in Complex Terrain Conditions Through Modeling Simulations.
The system is primarily suited for local scales (domains ranging from 5 to 30 km per side) up to mesoscale (domains on the order of hundreds of kilometers per side). It includes several preprocessing subsystems for:
- Defining calculation domains and extracting necessary territorial data (orography and land use).
- Defining emission sources (point, linear, and area sources).
- Managing meteorological input data.
The system features the SWIFT and SURFPRO meteorological models for complex terrain, which reconstruct three-dimensional mean fields (wind and temperature) and turbulence. These models feed into the three-dimensional Lagrangian particle dispersion code SPRAY, which reconstructs the dispersion of primary airborne pollutants in non-homogeneous and non-stationary conditions.
The software is suitable for both short-term episodic simulations and long-term annual climatological simulations, allowing for the comparison of results with current air quality regulations. Specifically, the system includes postprocessing software that enables the calculation of statistical indicators (averages, percentiles) on concentrations, graphical visualization (of meteorological inputs, concentration fields, and simulated computational particles), and the extraction of results at specific receptor points.
