Air Pollution Mapping
Using our IMMI software, Wölfel offers a series of services in air-pollution assessment. The following air-dispersion models are used:
- basic Gaussian plume model
- advanced Gaussian plume model (compliant with VDI 3782-1) and Canyon-Plume-Box model
- Lagrangian model (compliant with both VDI 3945-3 and the German TA-Luft "Technical Instructions Air") with wind-field pre-processor
- Austrian Gaussian plume model (compliant with ÖNORM M 9440) and Stern-Giebel near-field model
These models can be used to determine pollution concentrations of all typical air-pollutants taking into account meteorological conditions.
- Air-pollution modelling with IMMI using either Gaussian or Lagrangian model
Air-dispersion modelling applications
Applications:
- regulatory modelling
- permitting
- EU air-pollution directive and daughter directives - regional air-pollution maps
- Environmental Impact Assessment (EIA)
- smal-scale (few sources, small area) to large-scale (many sources or networks of sources, large area)
