    • Brief Bio

    Dr. John T. Sullivan currently works in the Atmospheric Chemistry and Dynamics Laboratory at the NASA Goddard Space Flight Center (Greenbelt, MD). He is currently the NASA Tropospheric Ozone Lidar Network (TOLNet) project scientist. His expertise is in performing measurements of atmospheric constituents using active remote sensing techniques, such as lidar (light detection and ranging), for applications such as air quality, satellite validation, and stratospheric trends. Dr. Sullivan has been critical in designing, calibrating, and deploying  transportable lidars for measuring tropospheric and stratospheric ozone profiles in NASA campaigns, such as DISCOVER-AQ and KORUS-AQ and various NDACC intercomparison campaigns. He was awarded the NASA Postdoctoral Program (NPP) Fellowship to continue his contribution of novel observations of the atmosphere to further NASA’s science exploration. In 2017, he was named as the Early Career Scientist associated with the NASA Science Innovation Fund (SIF) supported Ozone Water-Land Environmental Transition Study (OWLETS) in the Tidewater, VA region. He transitioned to the PI for the 2018 OWLETS field deployment within the northern Chesapeake region and the Co-PI for the TRACER-AQ (Tracking Aerosol Convection interactions ExpeRiment - Air Quality) in the Houston, TX metropolitan area in 2021. His role within TOLNet is to guide an inter-agency cadre of scientists and researchers to provide high spatio-temporal observations of boundary layer and free tropospheric ozone to study the character of the atmospheric structure that can be used to better evaluate satellite retrievals and improve the processes in air-quality forecast and diagnostic models.

    Research Interests

    Atmospheric Monitoring

    Utilize spectral and optical properties of the atmosphere to monitor important atmospheric constituents relating to air quality and human health. Understand the photochemical and diurnal cycle of urban/anthropogenic pollutants and their impacts on the outdoor environment. Examine the effects of topography on pollutants, particularly in the presence of complex terrain such as mountains or coastlines. Utilize various established networks of pollutant monitors to infer statistically significant spatial and temporal gradients in pollution. Recognize the physical and chemical parameterization applied in air quality modeling and forecasting.
