Impact maps of current activities. Immission maps: average and maximum values (episodes)

The generation of immission maps requires having reliable databases of:

- Emission levels databases. Emission factors determined directly from the chimneys and/or diffuse positions

- Orographic databases

- Surface and mesoescalar (satelite data) meteorological databases

The abovementioned data allow the realization of the following immission maps:

- 98-percentile maps of the average hourly data through the year

- 98-percentile maps of the average hourly data for the different months of the year

- Maximum annual values maps

- Maximum mensal values maps

- Maximum and minimum values for hourly slot maps

- Evolution of the emissions impact throughout the 24 hours of the day

The emission factors obtained directly from the emission sources with chemical control enable a higher reliability in the emission impact maps determined through numerical modelling.
