Steve G. Brown

With Sonoma Technology since 2001, Steve’s work focuses on analyzing the composition and sources of air pollution in both the near-field and regional scales. He has led the development and delivery of numerous training sessions on data analysis, data validation, and receptor modeling, including the development of the U.S. EPA’s freely available receptor modeling tool, Positive Matrix Factorization (PMF). He coordinates projects applying receptor models to PM_2.5, volatile organic compounds, air toxics, and continuous instrument data including high resolution aerosol mass spectrometer data. Steve uses his knowledge of atmospheric chemistry and aerosols in a broad range of contexts, from the near-roadway environment to the transport of aerosols to the Arctic. He is an avid traveler, often exploring unfamiliar cultures and hiking in mountains around the world. Steve and his family enjoy gardening, learning new cooking techniques, and developing original recipes using fresh herbs and produce from their garden.
