Air pollution by aerosols


Aerosols dispersed in the atmosphere are composed of diverse solid particles and liquids. Aerosols are produced by various natural and anthropogenic sources. Natural sources are for example volcanic eruptions, vegetation fires, sea spray, dust as well as pollen and fungal spores. The main anthropogenic sources are industry, economy, traffic, private households, power stations and agriculture. For the protection of human health, threshold concentrations for the aerosol load have been implemented. If the reasons for a local aerosol load are analysed, the individual local sources need to be considered as well as the influence of aerosol transport from distant sources. Thereby weather, in particular wind and rain, has a strong influence on the aerosol load.

Climate change


Since the beginning of the industrialisation around 1850 combustion processes produce giant amounts of carbon dioxide in the atmosphere. These are assumed to represent the main cause for anthropogenic climate change, which is assumed to be generally proven. However, what are the modifications of climate on Earth already taken place and which modifications are expected in the future? How far do we need to be prepared for extreme events such as heat waves, floodings and heavy storms? How reliable are scenario simulations presented by climate scientists? These questions and more are subject of my advice, evaluation, review, presentation and education activities.
