Summary

Dr. Buckley joined the Atmospheric Technologies Group (ATG) of the Savannah River National Laboratory (SRNL) as a postdoctoral research fellow in 1994. This followed research related to aerosol mechanics and numerical studies of solute transport in groundwater performed at the Particulate Systems Research Center (PSRC) at the University of Missouri in Columbia. Since joining the ATG, Dr. Buckley has helped design and to implement a prognostic atmospheric modeling capability for the southeast United States, as well as developing a system for archiving and using meteorological data from worldwide sources for applications related to non-proliferation and emergency response. He has extensive experience in modeling atmospheric dynamics, with applications to transport and dispersion modeling. More recently, he has interacted with various sponsors of work related to transport and dispersion in non-proliferation applications, directed sub-contractors in programs related to non-proliferation, and performed research with ensemble modeling techniques.

Summary

Mr. Hunter joined the Savannah River National Laboratory’s Atmospheric Technologies Group (ATG) in 1987. Prior to becoming manager of ATG in 2007, his primary responsibility was the development and operational implementation of consequence assessment modeling technologies for the SRS Emergency Response Program, and to provide expert technical advice and training on issues in consequence assessment to Savannah River site, state, and local emergency management officials. He lead the effort to fully incorporate meteorological analysis and forecasts from a 3-D mesoscale model into the consequence assessment process, including the capability to utilize regional contaminant deposition predictions from a Lagrangian particle dispersion model for performing near real-time assessments of ingestion pathway dose. The SRS was the first local site in the DOE complex to have this capability. In 2005, Mr. Hunter coordinated ATG’s response to a train derailment in Graniteville, SC resulting in a major release of chlorine to the environment. This work included support to the U. S. Justice Department for a study requiring a detailed modeling analysis of the airborne chlorine release followed by the absorption and transport of chlorine in an adjacent creek.

Mr. Hunter continues to provide expert consultations for SRS emergency management, nuclear safety, and regulatory compliance. This work includes the development of climatological and air quality sections of numerous SRS-specific Environmental Impact Statements and Design Safety Analysis Reports and air quality modeling analyses for SRS air permits, compliance with occupational exposure standards, and public health risk assessments. He recently lead an air modeling analysis for the underground ventilation system of DOE’s Waste Isolation Pilot Plant following the February 2014 waste drum fire event to estimate event source term. Mr. Hunter also coordinated development and operation of ATG’s meteorological forecast facility to support SRS routine operations, responses to severe weather events, and U. S. Forest Service’s wildland fire management activities at SRS. He led the initial development of a comprehensive web page to disseminate meteorological information and forecasts to the SRS workforce, and developed a unique computer algorithm to calculate, and post in real-time, wet bulb globe temperature for heat stress assessments using standard meteorological measurements. A copyright (#981-828) for the ‘WBGT Calculator’ was issued in 2000.

Summary

Dr. Viner joined the ATG in 2011 after receiving his doctoral degree in Agricultural Meteorology at Iowa State University where he used atmospheric transport models to predict airborne pollen dispersion and the potential for cross-pollinations between genetically-modified and conventional crops. At SRNL, his research has focused on airborne dispersion of particles in the atmospheric boundary layer as it applies to radiological particles and smoke from prescribed fires. His current research focuses on the impacts of the forest environment on airborne plumes to determine appropriate deposition estimates over the forest. Other work includes studying the effect of prescribed fires on the health effects of emergency response personnel and nearby communities as well as how it affects local carbon cycle dynamics within the forested environment at the Savannah River Site. He also provides support to the daily forecasting and emergency response operations at SRNL.

Summary

Dr. Werth joined the Atmospheric Technologies Group (ATG) of the Savannah River National Laboratory (SRNL) as a Senior Scientist in 2006. His interest has always been in the dynamics of the atmosphere, particularly with regards to his graduate work. Previously, he had been studying the effects of tropical deforestation on the local and global climate using a global climate model, noting how a surface change in the tropics could affect locations throughout the world. His research now focuses on the mesoscale climate and the evolution of the nocturnal boundary layer. In the time since his arrival, he has published a quality check of the Global Forecast System, a study of the nocturnal boundary layer and low level jet over Oklahoma, and a study of evolutionary programming methods to improve mesoscale models. He has also become involved in the statistical downscaling of global climate model data as applied to site operations and in developing a software tool to estimate the wildfire threat faced by home owners.
