40 years of experience in environmental sciences from air chemistry, sulphur chemistry and photochemical secondary products like ozone, H2O2 and other climate relevant components to aerosol research. Currently active in aerosol research on sources and distribution of ultrafine particles acting as cloud condensation nuclei and thus relevant for rainfall modification. Worldwide airborne research as pilot and scientist using small environmental research aircraft (also the worlds smallest manned environmental research aircraft) with a major focus on areas with apparent strongly modified rainfall patterns, drought and torrential rains, within the last decades.
