Rainer’s general interest is the study of atmospheric chemistry in air quality and climate science, using a combination of in-situ and remote sensing measurement techniques, which he and his group are developing and deploying in polluted urban and pristine atmospheric environments from ships, research aircrafts, and autonomous ground-based networks, and in simulation chamber experiments to develop and test the mechanistic understanding represented in atmospheric models used to manage air resources and climate.
