Air quality is a main problem of the civilization. Therefore, models predicting air pollution become more and more important. And this is quite easy. Let Aurora work together with albatross, and you will get good predictions. Of course I am referring to the paper of Carolien Beckx et al. (2009) and ALBATROSS and AURORA are models: A Learning-Based Transportation Oriented Simulation System and Air quality modelling in Urban Regions using an Optimal Resolution Approach. ALBATROSS is an activity-based model which predicts people's travel behaviour and the resulting vehicle emissions. It is based on approximately 10,000 person-day activity-diaries of Dutch. The predictions of vehicle emissions can be used as input for the air quality model AURORA. As “prognostic 3-dimensional Eulerian model of the atmosphere”, AURORA predicts how air pollutants (gas and particla) are transported in the air, including physical changes and chemical reactions which generate new pollutants. Using meterological parameters like wind, temperature, humidity, precipitation, radiation,…, AURORA calculates 3-dimensional concentration fields for different pollutants. Beckx et al. (2009) tested this model combination by comparing the model predictions for three different pollutants with real air quality data measured in different stations all over the Netherlands. Inside the country, the agreement between modelled and observed concentrations varied between the different pollutants but was sufficient for all of them. The only problems are the borders of the Netherlands, maybe because of wrong calculation of the contribution of foreign traffic. Maybe they underestimated how many people like to visit the Netherlands? The contribution of activity-based transport models to air quality modelling: a validation of the ALBATROSS–AURORA model chain
