Air pollution in Amsterdam with OMI + TROPOMI


Ten to fifteen thousand people in the Netherlands die every year as a result of noise or air pollution. The health risks are particularly great in and around Amsterdam.

At the moment the best satellite instrument for measuring air quality is the Dutch TROPOMI instrument, which was launched at the European Space Agency in 2017. At 7 km x 3.5 km, this instrument has more than six times higher spatial resolution than its predecessor, the OMI instrument. One of the most important aspects of air pollution reduction is examining which policies are most effective in controlling emissions into the atmosphere. This can be achieved through trend monitoring. Unfortunately, high-resolution satellite data has only been available recently, making a detailed trend analysis at regional level for 2017 impossible.

Special projects arise together

Our scientists wanted to give the old OMI data extra value.

Smart algorithms make it possible to get more out of TROPOMI.

The first series of results with pollution over time in nearly 500 cities.

Recently, Sobolt, supported by the Copernicus Incubation Program, applied deep learning to convert the historical OMI data into the same resolution as the TROPOMI data. With these improved OMI observations, new trends and patterns in air pollution can be identified. The artificially improved OMI data was validated on the basis of real TROPOMI data by researchers from Utrecht University and Erasmus University Rotterdam. The improved data represents realistic air quality data with a similar resolution to the TROPOMI data.
