GEIA is sad to announce the passing of Professor Donald Stedman of the University of Denver. Don was one of our esteemed colleagues and a significant contributor to characterizing the important role of emissions in understanding air quality and climate change. We have many fond memories of Don’s stimulating, and sometimes humorous, contributions to GEIA’s meetings, mostly recently at the conference in Boulder in 2014.
His obituary, prepared by his wife Hazel, is provided here. We also are including this extensive list of references (https://www.researchgate.net/profile/Donald_Stedman) as a small way of acknowledging his many contributions to emissions knowledge and, more generally, to environmental science.
