Dispersion Modeling
The KEMA-STACKS model enables the calculation and visualization of dispersion of pollutants like SO2, NOx, fine dust and odor
KEMA-STACKS translates the emission contributions of aviation, road traffic, industry and all other relevant sources into hourly and averaged concentrations. The tool is based on detailed meteorological data and incorporates the most recent methodology concerning dispersion modeling. The tool can be adapted to your specific need and can deal with extremely complex scenarios beyond the capabilities of standard software tools.
Aviation emissions
Environmental impact assessments are form the critical start and path in the decision making process on airport and air traffic developments. Future growth could be limited due to environmental constraints. Those constraints used to be noise related, but emissions and local air quality are getting more and more restrictive, especially for CO2, NOx, PM10 (fine dust) and odor. Detailed insight in aviation related contributions to the local air quality or the effect of mitigating measures is of paramount importance for the management of airports and air traffic. NLR and KEMA, being two world class players in their field of expertise have joined forces together bringing a solution to deliver an integrated and complete insight to asses and manage local air quality around your airport. The solution has been successfully applied for Schiphol Amsterdam Airport and airports of the Royal Dutch Air Force.
Shipping emissions
To model the local air quality in harbors the PM10- and NOx-emissions from ships have to be included in the assessments. Unlike as for stationary sources there is no generally accepted modeling approach to include the shipping emissions. As a result an original approach had to be developed to incorporate the shipping emissions in our air quality calculation model KEMA-STACKS. Three different ‘emission-modes’ can be discriminated for ships in harbors:
- passage or transit
- maneuvering
- moored with generators running.
