Jenny Hand

Title: Senior Research Scientist, Colorado State University



Dr. Jenny Hand is Senior Research Scientist and Fellow at the Cooperative Institute for Research in the Atmosphere (CIRA) at Colorado State University. Her research interests include characterizing the physico-chemical, radiative, and hygroscopic properties of atmospheric aerosols using techniques ranging from single-particle analysis to remote sensing. Her research also focuses on understanding the spatial and temporal variability of speciated aerosols across the United States by integrating data from large long-term U.S. monitoring networks such as the IMPROVE network, EPA’s Chemical Speciation Network (CSN), and EPA’s FRM and PM10 networks. Other interests include investigating long-term trends in aerosols and visibility degradation in relation to emission reductions, and the role of fine dust, coarse mass, and smoke on the status and trends of the aerosol mass budget and visibility across the U.S. Since 2008, she has served as the principal investigator on a cooperative agreement between CIRA and the National Park Service to characterize visibility degradation at national parks, to provide analysis in support of EPA’s Regional Haze Rule, and to perform regional air quality modeling to understand excess nitrogen deposition in remote regions across the United States. Dr. Hand has chaired and co-chaired committees of the Air and Waste Management Association and currently co-chairs the Atmospheric Processes Division.
