Summary
Dr. Chiswell joined the Atmospheric Technologies Group (ATG) of the Savannah River National Laboratory (SRNL) in 2008 and is responsible for research and development of technology in a wide range of atmospheric science contexts, including meteorological modeling, emergency response, data collection and analysis, and site forecasting. He is the developer of the data-ingest and dissemination system for ATG’s real-time meteorological data streams used in support of operational SRS and global forecast products and has developed automated Lidar based boundary layer height measurements used operationally for SRS forecasts, Emergency Response and atmospheric transport, the USDA Forest Service controlled burn program, and regulatory air quality requirements. He is active in developing and deploying advanced, high-performance computer simulation models for assessing downwind nuclear and contaminant transport, and inverse source attribution from observed measurements of signature materials emitted in the nuclear fuel cycle. He currently leads environmental fate and transport modeling work for several Defense Nuclear Non-proliferation Research and Development projects.
Prior to joining SRNL, Dr. Chiswell was responsible for software development and support of software and data systems employed at universities and research institutions worldwide. Prior to joining SRNL, Dr. Chiswell was responsible for software development and support of software and data systems utilized by over 200 universities and research institutions worldwide including GEMPAK meteorological analysis and display package and the Local Data Manager (LDM) application. He developed the Unidata NOAAPORT satellite data acquisition system used to obtain and distribute real-time meteorological data via the LDM Internet Data Distribution (IDD) network linking sites worldwide. Steve developed and coordinated delivery of numerous data streams and provided technical expertise in data products and formats, including high resolution model data (CONDUIT) from NOAA/NCEP, Global Positioning System radio occultation products (COSMIC), and THORPEX Interactive Grand Global Ensemble (TIGGE). He was nominated 3 times for UCAR’s annual technical achievement award and received special recognition as a member of the LDM6 development team. Dr. Chiswell’s research activities include operational atmospheric numerical modeling systems, development of atmospheric water vapor retrieval techniques from Global Positioning System (GPS) satellite measurements, in-situ Lagrangian measurements and cloud chemistry modeling. He has participated in numerous field projects including ACE, ASTEX, GPS-STORM, and EPA-Mountain Cloud Chemistry.
