PNNL

Steven J Smith is an Earth Scientist at the Joint Global Change Research Institute (a.k.a. PNNL Global Change Division) in College Park, MD and a Research Professor at the University of Maryland. Smith’s research has focused on long-term socioeconomic scenarios, the interface between socioeconomic systems and the Earth system, and interactions between air pollution and forcing. Smith is co-principal investigator of the Community Earth-atmosphere Data System (CEDS) project that produces global historical air pollutant emissions over the industrial era (1750-present). CEDS provides the historical forcing data for Earth system and atmospheric chemistry models around the globe, including DOE's Energy Exascale Earth System Model (E3SM). Smith also works with the Global Change Analysis Model (GCAM), which he and collaborators are using to examine multi-sector interactions between the energy system and air-pollutant emissions from global to regional scales. Smith also contributes to national and international assessment activities and is a member of the scientific steering committee for the Global Emissions InitiAtive (GEIA).
