It directly measures the NO2- concentration in the exhaust plume under actual driving conditions. Depending on its age, condition and even engine, how much does an individual vehicle pollute the urban air? Researchers from Heidelberg University are looking into the matter. The team led by environmental physicist Dr. Denis Pöhler has develope
