Dorothy Koch is the Director of the Weather Program Office (WPO) within the National Oceanic and Atmospheric Administration's (NOAA) Oceanic and Atmospheric Research (OAR) Line Office. She is honored to lead this talented and diverse team that is responsible for funding and fostering the advances in weather research that is vital for preparing the nation for the increasingly severe and impactful weather. WPO's scope covers the weather value chain, from observations, forecast and Earth system modeling, forecast product development and testing, and the social science needed to ensure successful forecast outcomes. WPO support community modeling activities, particularly the Unified Forecast System (UFS). As OAR's Weather Portfolio Steward, Koch coordinates NoAA weather programs and laboratories. As Chair of the NOAA Modeling Team, she leads the coordination of modeling activities across NOAA. Prior to working in OAR, Koch directed the Modeling Division in NOAA's National Weather Service (2019-2021), she managed the Earth System Modeling program at the Department of Energy (2010-2019), and she developed the aerosol model and studied aerosol-climate interactions using the NASA Goddard Institute for Space Studies' Global Climate Modeling (1995-2010). She served as a Lead Author for the Intergovernmental Panel on Climate Change 5th Assessment Report (IPCC AR4), published over 85 peer-reviewed publications, and was listed among Thomson Reuters' Highly Cited Researchers for 4 years. Koch earned her PhD from Yale University and her B.S. from the University of Wisconsin-Madison, both in Geology and Geophysics.
