      Sunyoung Park
      (Kyungpook National University, Republic of Korea)

      • Biography

      Sunyoung Park is professor of department of oceanography at Kyungpook National University. She obtained B.S. degree (1995) and M.S. degree (1997) from Seoul National University and Ph.D. degree (2005) in University of California, Berkeley. Her research interests are the biogeochemical cycles of the major greenhouse gases (GHGs), focusing on sources, sinks, and source/sink distributions of these gases, and the chemistry related to their formation and destruction. Her recent research topics also emphasize man-made halogenated compounds (CFCs, HCFCs, HFCs, and PFCs) - stratospheric ozone-depleting substances and/or GHGs by suggesting a significant increase in the emissions of most halocarbons in East Asia.

    • Session F. Environmental and human health effects of atmospheric ozone and UV

      "Mapping Global Ground-Level Ozone Concentrations for 1990 to 2017 to Support Health Impact Assessment"

      Jason West
      (Department of Environmental Sciences and Engineering, University of North Carolina, Chapel Hill, North Carolina, USA)

      • Biography

      Dr. J. Jason West conducts interdisciplinary research addressing air pollution and climate change by using models of atmospheric chemistry and transport and tools for quantitative policy analysis. His work aims to understand the relationships between air pollution and climate change and their relevance for science and policy on local through global scales.
      Using computer models, Dr. West is currently exploring the effects of changes in emissions on global air quality (ozone and particulate matter), the international transport of air pollutants, the health effects of air pollution, the effects of climate change on air quality and the radiative forcing of climate.
      Recently, Dr. West led the first study of the co-benefits of greenhouse gas (GHG) mitigation for air quality and human health to use global atmospheric models and future scenarios; results showed that the monetized co-benefits exceeded previous co-benefits estimates and exceeded the global costs of GHG mitigation through 2050.
