Environmental Modelling – Wind Model, incl. Gas Reactions
• NOX concentration
• SW wind weak
• NO PHOTOACTIVITY
• NOX concentration
• SW wind weak
• HIGH PHOTOACTIVITY
Prof. Dr. Michael Bruse, ENVI-met.com, Essen
Deposition rate: 0,2 cm/s
It is possible to reduce the concentration of NOX up to 12%.

Self Cleaning (Adsorbed Organics) and Air Cleaning (VOC and NOX)
Simulation Example
Fronts, roofs, walk – used for NO2,O3 destruction;
Average deposition rate 0,4 cm/s => in average 30% decrease of air pollution per
year <=> 100 days of total prohibition of heating and driving (fossil energy)
