Chemistry and Climate
 

The mission of the Chemistry and Climate division is to quantify, understand and predict anthropogenic and natural changes in atmospheric composition and their consequences for climate, air quality and ultraviolet radiation.

The main activity is the improvement of models of the life cycles of non-CO2 greenhouse gases, air pollutants, aerosols and their precursors in order to produce accurate short-term air quality forecasts, long-term scenarios for the future and reconstructions of palaeoclimates.


Latest news
KNMI has recently been involved in a comparison of the performance of different lightning parameterizations used in large scale 3D chemistry transport models over Africa during the West African Monsoon period. It was found that the contribution of LiNOx is most important over the tropical Atlantic, with convective mixing being more important in the upper troposphere over Africa.
